Poll Result: Java Technologies Employment Market

This past week's java.net poll on the Java technologies job market implies that the global economic downturn is far from over, at least for Java developers. In total, 275 votes were cast. Here is the actual question and the results:

What's the current status of the Java technologies employment market?

20.3% (56 votes) - Excellent, plenty of opportunities

46.9% (129 votes) - Stable, I have enough work

6.9% (19 votes) - Better than 6 months ago

22.9% (63 votes) - Still not good

2.9% (8 votes) - Other

So, about 1/3 of the responses were for options that state that imply that the Java employment market is in a recession. Only 2/3 of the votes state that the person has enough work.

Mu posted the comment:

This is an oddly constructed poll: The employment market has currently dried up. Ergo, none of the responses apply

Cajo replied that, in this case, the "Other" category applies. I think Mu would have prefered an option "There currently is no Java technologies employment market," or something like that. Globally, there surely is a Java technologies market, since 20% of respondants are seeing plenty of opportunities. But, in different localities, there may well be virtually no market at all for Java skills and experience.

In a healthy economy, I would expect the "Stable" and "Excellent" categories to garner a combined 95% of the vote. At the 67% level reflected by this poll (which, admittedly, is not scientific), there are a lot of people who are unemployed or under-employed.

In a java.net poll from exactly one year ago, 34% of respondants said that job prospects in their field had gotten better over the past year, and 20% said prospects had gotten worse. And in an August 2006 poll, 75% of respondants were working in a mode that included frequent "time crunches" (emergency situations requiring much more work than normal, to meet release deadlines, etc.).

These polls all asked different questions, but they all indicate the overall level of vibrancy in the Java technologies employment marketplace. In 2006, the experience of too much work to get done in the available time was common. That's certainly not the case today for many Java developers. Of course, again, these are not scientifically administered polls...

New poll: Have you tried out NetBeans Version 6.7?

This week's poll asks Have you tried out NetBeans Version 6.7? The much-anticipated NetBeans 6.7 release came out a few days ago. Are you already using it? Do you plan to try it out soon? Let us know by voting.

In Java Today, Danny Coward posted JavaFX: gr8 2 c on fonz: "What with the release of JavaFX 1.2 and JavaFX phones on sale to developers, and on view, for example here and here, the fact that the JavaFX language and common APIs are the same whether you are on the desktop or on a mobile device (or a TV set top box) is worth chatting about."

Kirill Grouchnikov demonstrates Project Marble - augmented reality in Java with JMF, Java3D, NYArToolkit and Trident: "Today i'm going to talk about setting up the development environment for running the augmented reality demo shown in this video from my previous post: Here are the steps..."

Arun Gupta provides quotes from developers in Rails on GlassFish - "most performant of all", "simpler and just works", "blazing speed": "Here are some quotes about running Rails applications on GlassFish from user@jruby mailing list: 1) I find the glassfish gem to be the most performant of all -- and I don't need to war-up my app. 2) I also have some mongrel cluster stuff, but glassfish is simpler and just works. 3) Voila...blazing speed, can handle lots of traffic..."

In today's Weblogs, David Walend writes about Event Based Programming in JavaFX: "I decided to try my hand at some JavaFX programming to see what the language had to offer. Two of the key features of JavaFX are its ability to bind to data, and its access to all Java libraries. I used that to see how it handles for event-based programming. I built this minesweeper game, enjoyed using bind and on replace, and found myself wishing for more."

Carol McDonald recaps her June events in 2 JavaOne Hands On Labs , Sun Technology Exchange, Java Technology Day Israel, and Java Day Turkey: "I had a very busy June, I gave two Hands on Labs at JavaOne, two sessions at the Sun Technology Exchange, three sessions at Java Technology Day in Tel Aviv Israel, and one session at Java Day in Istanbul Turkey."

And Harold Carr announces My CommunityOne 2009 presentation is online: "My CommunityOne 2009 presentation is now available online: 'S305138: Metro Web Services, NetBeans IDE, GlassFish Application Server, and OpenSSO in Action with Amazon WS, Azure, and Office'"

In the Forums, pccontact has a question about Glassfish Performance??: "Dear all, I have a SOAP application which doing some work takes about 1-4 secs to complete then response back to client. and the request and reply SOAP size is about 10K bytes long. My Glassfish is on a Q8200 4 core CPU with 4GB RAM on Cent OS 5.3. I use Threads.Sleep(1000) to simulate the process. The glassfish only can response 500 TPS(response per second back to client). I used SOAP UI to open 1024 threads(actually, 512-1024 get almost the same response TPS) for concurrent requests. If I use Threads.Sleep(2000) then the response only about half 250 TPS..."

wasedaxiao is seeing an open jdk7 build error: "I am building open jdk 7 on my Vista PC. Although I found j2sdk-image was successfully generated(I can launch java, javac under it) but the terminal prompot output the following errors. Could some please point where the problem exists? Constructing Javadoc information... ..\..\..\..\src\share\classes\javax\swing\JTabbedPane.java:651: cannot find symbol @Transient..."

And klauern asks if it's Possible to set http listener with web application at / context?: "I've been banging my head against this problem, so I thought before I start making too many changes or add any more frustration, I should ask whether it is even possible. I have a Glassfish V3 Prelude server set up on our environment that is listening on port 8070. Specific to this, I have deployed Hudson to it at context /hudson. So, the Hudson application can be reached at: http://localhost:8070/hudson Is it possible to set a specific http listener to be dedicated to only one web application?..."

The current Spotlight is the Christine Montilla Dorffi's article "2009 JavaOne Conference Wrap-Up: A Solid Show": 'The JavaOne conference is the kind of event where the declaration "Classpath is dead!" causes hundreds of people to applaud soundly and hoot their approval. We're talking hardcore, middleware-loving, certified-geeky Javaheads coming together to share their love of -- and frustrations over -- the Java programming language and platform, and the extended technology that it informs...'

The new java.net Poll asks "Have you tried out NetBeans Version 6.7?". The poll will run through next Thursday.

Our Feature Articles include a new article by John Ferguson Smart, Grails and Continuous Integration: An Essential Combo, which shows how to set up a Continuous Integration (CI) build job to compile and test your Grails application in Hudson, for automated continuous integration. We're also featuring Felipe Gaucho's article, Exposing Domain Models through the RESTful Service Interface, Part 1, which describes domain models and demonstrates how to create a generic CRUD application.

The latest Java Mobility Podcast is Java Mobility Podcast 81: JTDF, in which Eric Areseneau talks about Victor D'yakov talks about the new Java Device Testing Framework project in the Mobile & Embedded Community.

How to Start and Grow a JUG: Community Corner 2009 Podcast

Have you ever thought about starting a Java User Group? Matt Stine spoke with me at JavaOne about his experiences with starting and growing the Memphis/Mid-South Java User Group in a java.net Community Corner podcast titled JUG Leadership: Lessons Learned. Go to Matt's blog to get the slides so you can follow along as you listen to the podcast.

Matt works at St. Jude's Children's Research Hospital in Memphis, Tennessee. He started the Memphis/Mid-South JUG in 2007. The JUG reaches out to three states: Tennessee, Arkansas, and Mississippi. Matt started the JUG soon after JavaOne 2007. He put up a web site, and serendipitously the JUG's biggest sponsor saw the web site and expressed interest in providing support almost immediately. Carol McDonald also found out about the new JUG and came in to speak early on.

So, Matt doesn't feel like it was all his doing that the JUG got off to a strong start. But keeping the group going is something I think he can take a lot of credit for. He had the experience of belonging to a JUG in the 1990s. That JUG did not continue, so Matt was quite aware that there's more to keeping a JUG going than just creating it.

Matt's two years of experience with founding and growing the Memphis/Mid-South JUG led to a list of eight key points of advice, the lessons learned that he offers to other JUG leaders and anyone who might be thinking of starting a JUG. I can't go into all the details Matt presented in our almost 26-minute talk in a blog post, but here are Matt's eight focal points for starting and growing a JUG:

Web Presence
Cultivate Sponsorship
Network
Grassroots Marketing
Encourage Participation
Wide Topic Spectrum
Never Say No
Stay the Course

It was a very interesting interview for me. I'm not a JUG leader, but I do think there are similarities between my role as java.net editor and what a JUG leader tries to accomplish. We're both trying to bring people together and stimulate participation and community that is hopefully beneficial to everyone who participates. In fact, as I sit here writing as I re-listen to the podcast, I find myself wanting to find my local JUG (I'm in rural Northeastern Connecticut, the "Quiet Corner"), schedule a visit, and maybe even give a talk of some type...

It was great to have Matt in for the JUG Leadership: Lessons Learned podcast. I learned a lot, and I think anyone who is considering starting a JUG or who currently leads a JUG will come away with valuable information from listening to the podcast.

You can find all the 2009 java.net Community Corner podcasts on our JavaOne Community Corner Podcast page.

In Java Today, In The ATM Object-Oriented Design and Implementation Case Study, In this java.net Community Corner 2009 podcast, educator, author, and Java Champion Paul Dietel presents an overview of "The ATM Object-Oriented Design and Implementation Case Study" from his book "Java: How to Program." Paul describes the presentation like this: "A key concept in object-oriented programming is the interactions among objects. Most programming textbooks show code examples that create and use one or two objects to demonstrate specific features of the language. In addition to small examples like these, our textbook Java How to Program, 8/e (published March 2009) presents an object-oriented design/UML 2 automated teller machine (ATM) case study and its complete code implementation. This ATM case study is a nice business example that students can relate to..."

PUJ, a JUG Contest: Community Corner Podcast

Felipe Gaucho talked about the Premio Universitaro Java (PUJ) competition with Jim Wright in a 16-minute java.net Community Corner podcast recorded at JavaOne. PUJ is:

an academic competition to promote the synergy between the academy goals and the market needs. The prize stimulates the students to submit their homework projects to analysis by IT experts - senior professionals who will evaluate the quality and the market adequateness of what the students are coding (the homeworks) in the local universities.

Felipe started the competition within his JUG in Ceara, Brazil as a means of bridging the gap between academia and industry. Each semester computer science students produce and enormous volume of applications. In the contest, the student's applications are submitted to teams that assess the applications. The evaluators include other students, professors, and industry experts.

Felipe considers what students produce as a product, and establishing communication between students and professionals stimulates the students themselves to consider their work in a more professional light. It's an idea that could be implemented by JUGs almost anywhere in the world.

The first year of the competition drew only five applicants -- a small number that had even Felipe wondering if his idea was going to succeed. But the contest drew significant interest from professors and industry professionals.

The second year's competition (which included a first prize of a paid trip to the DEVOXX conference) drew 25 submissions. The competition was intense, with many very high quality applications making it difficult for the judges to determine the winner. The winning application won by a single point over the second place entry.

Students are eagerly anticipating the third annual competition, asking Felipe when it's going to get started. Felipe has now created a PUJ web site. There you can find detailed instructions about the competition, along with a PUJ 2008 video.

Visit the PUJ, a Jug Contest, JavaOne 2009 Podcast page to listen to the complete 16-minute discussion between Felipe and Jim.

Java Tools Community Corner Podcast Features Duke's Choice Award Winners

When Java Tools Community Leaders Toni Epple and Fabiane Nardon invited the SQE (Software Quality Environment) Project team to participate in the Java Tools SQE Roundtable podcast at this year's JavaOne, they weren't planning on the Duke's Choice Awards being among the topics of conversation. But that was before the Duke for "Java Technology in Network Solutions" was awarded to ND SatCom for the NetBeans Satellite Tracking System. The tracking system occupies Sven Reimers and Florian Vogler each work day (ND SatCom has developed more than 1000 modules that run on top of NetBeans), while they push ahead with SQE project development at night and on weekends.

This isn't to say that there is no relationship between the NetBeans Satellite Tracking System and SQE. SQE itself is tightly integrated with NetBeans. Here's one reason why Sven and Florian both appreciate NetBeans: during the podcast, Fabiane asked if a lot of work was required to adapt SQE for the new NetBeans 6.7 platform. The answer? No work was required whatsoever, due to the backwards compatibility that is engineered into NetBeans.

SQE consists of several elements, including code defect analysis, metrics, and dependency analysis. When asked which SQE component they the most important, both Sven and Florian agreed on the FindBugs code defect tool. It provides free and fast analysis of code, immediately locating annoying bugs that might otherwise occupy hours of a developer's time.

Right now, the SQE team consists of Sven and Florian. But, they are seeking help with the project. There are a lot of smaller items that could easily be tackled by someone who wants to make a contribution. Visit the SQE project site if you're interested in helping.

You can find the 2009 Community Corner podcasts as they are published (along with the podcasts from previous years) on the JavaOne Community Corner Podcast page.

In Java Today, NetBeans.org is proud to announce the availability of NetBeans IDE 6.7!

New features include integration with Project Kenai, a collaborative environment for developers to host their open-source projects; native Maven support, and Hudson integration. Building on the success of previous releases, NetBeans IDE 6.7 offers enhancements for Java, PHP, Ruby, JavaScript, Groovy and C/C++, and more. Additional highlights include a self-diagnostic Profiler, and support for SVG Rich Components, remote debugging in Ruby, and the latest version of GlassFish. The release also provides plug-in support for Zembly, a single registry and repository for popular Web APIs..."

Back from Jazoon, Danny Coward writes about Java ME Defragmentation: "For those of you concerned about Java ME fragmentation, you were probably pleased about the creation of JATAF - a group of mobile companies (and Sun) getting together to try to sort out the issues of differences in implementation, quality, and performance that even the best API specs can't always iron out..."

razvan_petrescu needs to Track client session in a WS implemeted as an EJB: "I was trying to implement WebService a stateless EJB, but I need to track client sessions, similar the way is it done in a servlet. Is this possible ? since I've realized that the container doesn't set any session on HttpServletRequest object, and the HTTP response does not contain any JSESSIONID. Of course, everything works fine if the WS is implemented a simple class running in the WebContainer, but forces me to use an indirection, because I want to have the business implemented as EJBs..."

And sandeepkumar03 finds that Pick Midlet not working in Resource Editor: "Hi All, I am using LWUIT_20080814 build resource editor. I wanted to do the styling by selecting the Midlet.

In the Forums, jmartinloi has a questions regarding Specifiying Address / Interface for cluster node communication: "Hi folks, Is it possible to specify the interface or IP address used for cluster node communication? In our data centers, we use eth0 as our management network (backups, monitoring, etc) and eth1 and higher for everything else. The problem I'm seeing is that when non-DAS nodes are advertising their locations to one another, they are doing so through eth0, which has a very restrictive set of firewall (iptables) rules for traffic. eth1 is open to the network segment that each of the cluster nodes belong to. When I disable iptables and effectively open up eth0, the nodes communicate properly and the cluster works. When I enable iptables, it fails again. To sum it up..."

]]> The first of many Community Corner podcasts that were recorded at JavaOne 2009 has been released: the Java Tools SQE Roundtable...

Poll Result: More Java.net Project and Community Focus Desired

A significant majority of participants in the latest java.net poll would like to see increased project and community content on java.net. In particular, the poll participants would like to see more project demos and tutorials.

A total of 188 votes were cast. Here are the final results:

Which project and community (P/C) content would you like to see more of on java.net?

11.7% (22 votes) - P/C news features

3.7% (7 voters) - Interviews with P/C/ leaders

5.3% (10 votes) - P/C-related podcasts

57.9% (109 votes) - Project demos/tutorials

15.4% (29 votes) - All of the above

4.2% (8 votes) - The current coverage is fine

1.5% (3 votes) - Other (please leave comment)

Two comments were posted. Peter noted:

Before anything is changed on the front page, the absolutely abysmal speed of java.net and dev.java.net need to be solved.

java.net Community Manager Sonya Barry replied to Peter's comment, providing a status update on the ongoing efforts to address the performance issues:

You're absolutely right on the performance issue. We've been working on it for a while now. We are currently working on removing SSL from across the site (except log-in pages and CVS/SVN access) which will speed things up significantly on it's own. Once that's done we'll also be able to cache project pages should continue to improve performance. These changes are expected to be complete in September.

The poll result is not that surprising, looked at in retrospect. But, I would not have predicted this exact result when I created the poll last week. Java.net is a developer community, and the poll result reflects that clearly: developers want to see more detailed information especially about the java.net software projects. This is a call to the project teams to spend more time publicizing their work, and making it more accessible to the broader community, through tutorials and published and/or downloadable demos. Project owners could publish more announcements on their project site, and use a java.net blog to publish tutorials, demos, etc. Clearly the java.net community would be pleased if this happened.

Meanwhile, there are a few things that can be done by me, as java.net editor. First, anyone who has news related to a java.net project or community can let me know about it, either through email, a comment posted to one of my editor's blogs, or using the java.net Submit Content page. Secondly, I will be actively seeking input from community and project leaders, for news items, and to do interviews and possibly podcasts, since the poll result does show that these would interest quite a lot of people.

A lot of changes to java.net are in the works. We'd like those changes to reflect the needs and desires of the java.net community. So please, always feel free to suggest things you'd like to see on the site.

Jazoon09: Alois Reitbauer on Scalability

Harold Carr attended Alois Reitbauer's session "Why applications do not scale" at Jazoon09, and posted detailed notes in his blog. If you haven't done much work with scaling systems, some of the points Alois made might surprise you. For example:

Scalability does not improve performance

Increases complexity and degrades performance

Slower in single user mode

performance is still an issue

How can this be? Well, to understand this, you have to think about the difference between performance and throughput. Performance is actually a measure of throughput per unit something. Say you have a computer and you have a process that receives some kind of input and produces some kind of output. You could define your performance as being the amount of output data that is produced by that single machine in an hour. So:

Performance = OutputDataBytes per Hour

Now, let's say your application is a success, and more customers want to send you input data and receive your output data products. You're sufficiently successful that your one machine cannot process all the input data requests. What do you need to do? You need to scale your application.

"Easy!" you say. "I'll buy another computer!" Fine, so now you have two computers. But there are some problems:

how are you going to determine which computer receives which input requests?
what if you receive only a single giant request? How do you split that single request between your two computers? And if you're able to do this, how do you repackage the output into a single entity to send it back to the requestor?

Well, the answer is: you have to add new software to your application, overhead software that makes these assessments and performs these kind of tasks. Suddenly, your application has grown in size and complexity. So, is a bigger, more complex application, that performs more processing on the same amount of incoming data, going to have better performance or worse performance than a simpler application? Clearly, performance is worse in the bigger, more complex app, right?

And here's where our original definition of performance was incorrect. Performance is really the amount of throughput that a single node produces per unit time:

Performance = OutputDataBytes per Node per Hour

As soon as you introduce a second node and add overhead software to manage and coordinate the processing performed by each node, your performance drops, because you are doing more work per unit of output data.

So, if performance decreases, then why scale? Because even if your performance is reduced by 10%, your throughput can be increased. Your throughput, in our example, can be defined as the total amount of output data your entire system produces:

Throughtput = Total OutputDataBytes

So, here's the theoretical relationship between performance and throughput for an unscaled application running on one computer and a scaled application running on multiple computers:

Nodes	App Type	Performance Factor	Throughput
1	Unscaled	1.0	1.0
2	Scaled	0.9	1.8
3	Scaled	0.9	2.7
10	Scaled	0.9	9.0

Ah, but if only the real world was as simple as this! Because, in fact, as you add successively more machines, your overhead processing that scales your application inevitably begins to bump up against bottlenecks of various kinds. The greater the number of nodes, the lower your performance factor. Take a look at the "Limiting factors" section in Harold's notes.

A more realistic table might look like this:

Nodes	App Type	Performance Factor	Throughput
1	Unscaled	1.0	1.0
2	Scaled	0.9	1.8
3	Scaled	0.85	2.55
10	Scaled	0.7	7.0

In the bottom row, you've multiplied your number of machines by a factor of 10, but your throughput has increased only by a factor of 7. The "law of diminishing returns" has kicked in.

It looks like "Why applications do not scale" was a very interesting and enlightening session. You can learn a lot (or be re-reminded of a lot) just by reading Harold's notes. I'm glad he chose to document his Jazoon sessions so thoroughly!

Jazoon09

Jazoon09, the international conference on Java technology, is completing its second full day of sessions. Monday was community day, with two all-day events: GlassFish Community Day and OSGi DevCon Europe Community Day. Tuesday featured the formal opening session, with keynotes by Christian Frei and James Gosling.

As of right now (Wednesday morning, Eastern U.S. time), the conference front page features an article describing James's keynote:

Jazoon kicked off with a spirited re-mix of a pre-recorded Gosling interview on the early history of Java. Surprised by this introduction by his alter-ego, Gosling rolled with it, "I didn't know that was coming - kinda goofy, but fun".

Felipe Gaucho, who recently posted the Pocket guide to Jazoon 2009, was in attendance, and documented the highlights of James's talk, which included:

statistics (15 Million downloads per week)
the range of Java application (from tiny devices to highly scaled enterprise data centers like eBay and the Brazilian healthcare system)
JVM as the integration hub
GlassFish V3, NetBeans 6.7 and its integration with Kenai

and quite a bit more. See Felipe's post for the complete list and more detailed descriptions.

As you can see in today's highlighted blogs, Harold Carr was scheduled to speak at 1:30 Zurich time (with co-speaker Jiandong Guo) about Metro Web Services Security Usage Scenarios.

Today's keynote was given by Sun's Danny Coward, whose commentary (from The Planetarium) is often featured in our Java Today section. Thursday's morning keynote address will be given by Adrian Colyer of SpringSource. Then, in the afternoon, NASA's Linda Cureton will give the final conference keynote, followed by Christian Frei's formal conference wrap-up.

In Java Today, Harold Carr will be Speaking on Metro Security at Jazoon: "I will be speaking on Metro Security at Jazoon in Zurich on Wednesday June 24 at 1:30pm. "

Felipe Gaucho presents the Pocket guide to Jazoon 2009: "Java conferences are always a joy of technology and networking but sometimes we just miss its surroundings because it is quite difficult to concentrate in our lives while we are exposed to a large amount of cool information. Good meals, city attractions and a lot of interesting moments are just skipped in favor of the Java novelties on the stage. The more you participate of such events, the more you learn to offer your geek mood a chance to check different cultures and to learn different things. During the recent JavaOne I did not attended much extra-conference events..."

2009 JCP Program Awards and Videos

Felipe Gaucho attended the 2009 JCP Program Awards ceremony, and provides some videos of the event in his recent blog post. The awards ceremony took place during JavaOne.

I wasn't able to attend this event, so I did some reasearch on the award categories and winners. Here they are, with some links to help you get to know a bit more about the people and JSRs that won the awards in each category:

JCP Program Member of the Year: Apache Software Foundation
JCP Program Participant of the Year: Doug Lea (Doug is also a Java Champion)
Outstanding Spec Lead for Java SE/EE: Ed Burns
Most Innovative JSR for Java SE/EE: JSR-316: Java Platform, Enterprise Edition 6 (Java EE 6) Specification, which is led by Robert Chinnici and Bill Shannon
Outstanding Spec Lead for Java ME: Mike Milikich for JSR 271: Mobile Information Device Profile (MIDP) 3.0
Most Innovative JSR for Java ME: JSR 271: Mobile Information Device Profile (MIDP) 3.0

At JavaOne, I had the good fortune to record a podcast of the JCP roundtable that took place in the java.net booth as part of Community Corner 2009. It was a very interesting conversation (I expect that the podcast will be available soon) that included Patrick Curran, Ed Burns, and others.

The Java Community Process has come under a lot of fire. However, my experience is that open standards are critical for the long-term success of technologies and technology platforms. A standards body by necessity moves at a somewhat deliberate pace. During the roundtable at JavaOne, this was discussed at length, along with the reasons behind it, and the delicate balance between tracking new innovation, embodying it in standards (to better enable its application by a broader spectrum of developers), and getting too far ahead of what's new in a particular technology space. You don't want to stifle innovation by coming in too soon and defining standards before emerging technologies have sufficiently coalesced around a more or less clear mode of implementation and direction. Rather, there is a "sweet spot" (my term) where establishment of a standard is both timely and beneficial for the long-term advancement of the technology. Based on observing the roundtable at our Community Corner, it's clear to me that the JCP is very much aware of these issues, and takes their role in the long-term advancement of Java technologies very seriously.

I wish I had been able to attend this year's JCP Program Awards. I'm sure it must have been an interesting event. Thanks again to Felipe for attending and providing videos that capture some of the winning moments.

In Java Today, Felipe Gaucho shows us the JCP 2009 Annual Awards Winners (with videos): "Several pictures and short movies are here in the JavaOne folder, including the announcement of some of the winners of the 2009 JCP Program Awards 2009... Congratulations for all winners, and thanks SUN for the very nice party."

Eamonn McManus reports that JSR 255 (JMX API 2.0) is postponed: "Here is the text of the message I recently sent to the JSR 255 Expert Group, in my capacity as Specification Lead. 'Dear experts, I'm sure that you saw some months ago that our work on JSR 255 will not be part of the JDK 7 release (http://openjdk.java.net/projects/jdk7/features/). This decision was made here at Sun in order that some of the higher priority features could be properly resourced, in particular for the TCK work. So, we need to retarget our work for JDK 8...'"

Clive Brettingh responds Re: getting at the SOAPHeader directly from inside @WebMethod: "Well, I don't like to say never, but in several readings of the standard I have not noticed any specified way to access headers in the endpoint code (unless is a message mode Provider).I got the impression that headers are considered metadata that should be processed by handlers (unless header part); the handlers however, may pass the results of this processing to the endpoint via the message context (or other mechanisms like container authentication).

Inside the Java Store: Q & A

Josh Marinacci has been secretly working on a project that became one of the major announcements at this year's JavaOne: the Java Store. Last week he published The Java Store, a Q&A, as a supplement to the Java Warehouse FAQ. Regarding the Java Store, Josh notes:

I'm especially proud of it because I've been secretly working on the project for the past few months. Since the announcement I've gotten a lot of questions on the store and how it relates to the rest of the Java ecosystem.

First of all, Josh succinctly addresses the basic question that anyone who hasn't followed the story closely may have:

What's the one paragraph summary of what you've announced?

We have announced the private beta of the Java Store, a desktop client to let people browse and purchase desktop Java applications, and the open beta of the Java warehouse where developers can submit their apps for distribution. You can sign up to test out the store and warehouse today. Currently US only for both the store and the warehouse, with more countries coming soon.

Josh goes on to pose and answer questions such as "Can I make apps for the Java Store in languages other than JavaFX?" (Answer: yes); "When will you let me sell my apps?" (Answer: "As soon as we can. The store isn't open yet."); and "What about mobile apps and TV?" (Answer: "In the future there will be additional storefronts for TV and mobile").

Josh also responds to a question that has been on the minds of a great many developers since rumors of the Java Store began to circulate:

How will customers find my apps?

The desktop client you saw at JavaOne is only the first version. We are already hard at work adding new features to the store that will let customers find your apps. Features like searching, filtering, ratings and reviews. And eventually the Java Store will be distributed with Java itself, ensuring your apps can be found by nearly a billion people.

The last sentence is actually the key behind the entire Java Store strategy, in my view. Installing applications from the web is becoming increasingly common today -- to the extent that many users of such applications (e.g., games, etc.) don't necessarily realize they're actually installing something on their computer or mobile device. All they know is that there's an icon and when they click it they get to do what they want to do. Clearly, I'm talking about people who are not software engineering professionals here...

So, let's look at the Java Update process. When a "Java Update" bubble appears on my wife's screen, she knows that it's safe to let it perform its install (from the experience of me telling her it's safe, so long as it looks like the same "Java Update" bubble she's often seen before -- note that she doesn't just click "OK" for most such bubbles that pop up on her screen, and knows specifically to click "Cancel" or "No" for some of them). The future Java Update bubble will look at not only which Java is installed on the computer or device, but it will also look at the versions of Java Store applications you've installed, and tell you if there is a new version available. Meanwhile, the Java Store application itself may have capabilities to inform you about applications you might find interesting. Or, developers in the community might produce applications that performs these kinds of analysis, facilitating finding interesting and relevant Java Store applications, and distribute it using the Java Store.

The concept of the Java Store isn't astonishingly new, if you look at it simply as an elaborate software update system (akin to Windows Update). What's different about the Java Store, though, is that it is really a non-intrusive community platform for distributing applications that run in a JVM, supplemented with tools that let the user community talk about, rate, and find new applications. That's very different from Windows Update, which is really a corporate sales tool ("Hey, user! It's time to pony up some cash and upgrade to the latest Microsoft software release, don't you think?"). In this sense, in its style and approach, the Java Store is really a Web 2.0 platform centered on software applications. I like that!

In Java Today, Joshua Marinacci writes about a project he's been secretly working on, in The Java Store, a Q&A: "One of the big announcements at JavaOne was the Java Store. I'm especially proud of it because I've been secretly working on the project for the past few months. Since the announcement I've gotten a lot of questions on the store and how it relates to the rest of the Java ecosystem. To supplement the excellent FAQ I thought I'd answer a few questions..."

Marina Sum reports that OpenDS 2.0.0 Release Candidate 2 Ships: "OpenDS community manager and architect Ludo Poitou has announced the release of OpenDS 2.0.0 Release Candidate 2. Besides bug fixes, the release includes many new capabilities, including enhanced multimaster replication and recurring tasks. OpenDS 2.0 will follow shortly after the testing of RC 2 is complete..."

AND Jean-Francois Arcand reports Atmosphere 0.2 GA now available: "Finally, Atmosphere 0.2 released with support for annotations for REST application, improved support for Tomcat/Jetty/GlassFish, native support for JBossWeb 2.1.x, and EJB/External components broadcast lookup available." You can also see the official announcement.

And John O'Conner has news for developers who are Learning JavaFX?: "Long ago, I started a series called JavaFX Learning Curve Journal. Those articles/journals were on java.sun.com at the very beginning of the JavaFX project. I recently tried to find some of those articles, and I think they've been removed or..."

In the Forums, chrjohn asks When do I need Multicast, HADB, in-memory-replication on a cluster?: "Hi, for a project we want to use the clustering capability of Glassfish V2.1. There are some questions which arose, maybe someone can answer them or point me in the right direction. 1. The project does not have any HTTP sessions or SFSBs. So I guess I do not need the state replication via HADB or in-memory-replication? All I want is that the SLSBs and MDBs are highly available in the cluster, i.e. if one server fails then the beans from the other server are taking over. 2. I do not want JMS messages to get lost. I guess the broker can store the messages also in another data base. Or is HADB recommended for this? 3. Regarding multicasting: is this only used for the session replication feature? ..."

jtalbut has a problem where an EJB web service from WSDL doesn't work with external XSD: "Hi, I have a WSDL file that imports an XSD file (both attached, they originate from the book "SOA in Practice" but I've extracted the schema myself). In Netbeans I have an EJB Module project, and I use the "Web Service from WSDL" feature to create an EJB based on this WSDL file - the only change I make is to turn off the wrapped style and to write a trivial body to the function. When the web service is called all of the fields (in this example there is only one, I've got a bigger WSDL with more) in the GetCustomerAddress object are null. Before I extracted the XSD into a separate file the web service worked correctly..."

And Linda Schneider responds to questions Re: Delivery of JMS message in case of distributed transaction: "Conceptually I understand your problem is caused because the JMS update is faster than the database update, but I don't know of anyone in the real world who is having a similar issue. Actually, I'm not 100% sure why you are ever seeing this issue .. Are you *always* performing the database operation first ??? (you have to if you want to guarantee the right behavior). Are you running in a transaction ??? (not required, although it may help to pinpoint an issue). Here is my confusion .... I can see two possible ways to do this ..."

Poll: Majority Believes There Will Be a JavaOne Conference in 2010

A majority (57%) of respondants to this past week's java.net poll expect there to be a JavaOne conference in 2010. The specific question and results were:

Will there be a JavaOne Conference in 2010?

57.4% (189 votes) - Yes

10.3% (34 votes) - There will be a similar conference with a different name

12.4% (41 votes) - Probably not

7.2% (24 votes) - No

12.4% (41 votes) - I don't know; other

About two thirds believe there will either be a JavaOne conference or a similar conference with a different name, while 20% believe the days of JavaOne conferences are probably or definitely over. There was an unusually large number of votes for the catch-all category ("I don't know; other"): 12.4%, which was tied for second place among the voting options.

Of course, the not-explicitly-mentioned word in this poll was "Oracle." Two of the three posted comments were about Oracle: lumpynose thinks JavaOne will be folded into Oracle World, but denka notes "there's a chance European regulators will not let that acquisition happen."

shemnon wonders:

What if there is a JavaOne conference but with less focus on one of the particular stacks, like a JavaSE and JavaME focused conference with significantly lesser attention to JavaEE?

A lot of the people I interact with directly make the statement that the Java community is just too big for it not to find a suitable "home" with appropriate sponsorship. If you consider "JavaOne" to be Sun's trademark name for the big Java-centric conference in the Americas, it would seem readily possible that if there is such a conference in the future, it might be renamed. Acquisitions often result in rebranding of the "products" of the purchased entity.

Another question, though, is: do we still need a big annual Java-centric conference? Has JavaOne outlived its usefulness? Or is it still a highly valuable confluence of people and technologies?

New poll: changes in java.net content?

The new java.net poll asks you what changes you'd like to see in java.net's community- and project-related content. The specific question is:

Which project and community (P/C) content would you like to see more of on java.net?

I'll be tailoring my future efforts on the java.net home page and in my daily blogs based on the results of this poll, so please take advantage of the opportunity to express your opinion. Voting will be open through next Thursday, June 25.

In Java Today, Charles Humble wrote Project Coin Announces Second Candidate List: "Project Coin aims to make small language changes for Java 7 which simplify day to day coding for developers.

In the Forums, Joel Weight responds Re: [webtier] JSF - javax.faces.STATE_SAVING_METHOD: "Everything you say sounds like a misconfiguration of the load balancer to me. I would try running it outside the load balancer and see if you can reproduce the problem, then if it still occurs, you could look elsewhere. In our app, we have multiple forms on the page, and in client state saving the state is written to the response for each form so our simple pages ended up being a 2MB download for the client, so we went to server. We never had any problem losing state with either configuration. If you can reproduce it reliably only on certain pages, then faces-config could be the problem, but as I said, I would look at the load balancer first... "

jduprez has an issue with Corrupted XML (SOAP responses) under load: "Hello, still performing load tests of a Glassfish-hosted application exposing WebServices.

Actually I had to slightly change one of the classes in SVG Rich Components Framework but part from that everything seems to be OK..."

In today's Weblogs, Sahoo writes about Developing Hybrid (OSGi + Java EE) applications in GlassFish: "In my last blog, I mentioned about implementation of OSGi web container in GlassFish, but I didn't have time to show you some real examples. This time, I shall walk you through the steps of developing and deploying such a hybrid application in GlassFish v3."

Fabrizio Giudici warns that JavaFX binding is neat, but ... beware: "An interesting chains of discussions has been triggered about JavaFX features and how it can be possibly used beyond the GUI scope.Osvaldo has just published an interesting post.

userlab is working with Wonderland + JavaFX: "Hi everyone, I was wondering with the addition of JavaFX into the JVM family is there any project/work using JavaFX within Wonderland virtual worlds or is there plans on using the JavaFX platform in the future? I would be interested in starting a discussing and hearing all your thoughts on the + and - on using JavaFX in this context and maybe where we can take best advantage of its features. Just to get started I've thought it would be nice to have the client side UI written in JavaFX, for this would have the following benefits; - The UI could run within a browser and then be dragged off to be independent of that browser. (IE only) - The interface could be easily extended by none Java developers and be more rich in look-and-feel. - If the client side kept close to the core JavaFX library then it could run wherever the FX platform is or goes...

And ipsi asks about Options for Securing Client when Server has no wsp:Policy information?: "I have a web application running under Glassfish V2 UR2 (Java 1.5), and as part of that Application I need to call a remote web service. As far as I'm aware, that web service doesn't have any wsp:Policy information in the WSDL, and so I need an alternate way to secure it. The less code I have to write, the better. I've seen information regard wsit-security and {serviceName}Service.xml files, so I'm wondering if it would be as simple as taking the WSDL, adding all the required policy information (including the signed/encrypted parts and such), essentially including all the policy information that would normally be on the server side, and just allowing Metro/WSIT to pick that up. If that's possible, that'd be fantastic. For what it's worth, I did try that, but it didn't seem to find the wsit-client.xml file..."

New GlassFish ESB v2.1 Improves Scaling through Clustering

GlassFish ESB v2.1 has just been released. The new release features improved scaling through clustering, AIX 5.3 support, the new Intelligent Event Processor (IEP) Service Engine, and the new Scheduler Binding Component (BC).

I looked at the release notes to get a more detailed view of what's new and improved. Robustness and platform support stand out to me, along with the two highlighted new components.

The Intelligent Event Processor Service Engine "enables complex event processing (CEP) and event stream processing (ESP) using the Continuous Query Language (CQL)." A quick search of the GlassFish ESB documentation didn't turn up details about this, but a web search brought me to the OpenESB IEP page, which says:

IEP engine can send and receive events from all the external systems that Open ESB supports. The events from the Open ESB external systems can generate a cloud of events as well as streams of events. The IEP engine can analyze both these types of events. IEP uses Continuous Query Language (CQL) and a rich set of operators to analyze the events.

The page also includes an engine architecture diagram and overview, and points us to the IEP Wiki and the IEP User's Guide.

The new Scheduler Binding Component:

provides scheduling capabilities for initiating JBI services. The binding component is powered by http://www.opensymphony.com/quartz/, and allows you to schedule triggers to launch (consume) other JBI components, such as the File Binding Component. You can set these actions or processes to occur at specific times or break up activities to fit any schedule.

You can apply a simple trigger (time-interval), a cron trigger (like the Unix cron program), or a hybrid trigger (a cron that controls a simple trigger).

If you've developed software that requires guaranteed high availability on multiple platforms, you understand the significance when a large application adds support of new systems. GlassFish ESB 2.1 adds full operating system support of OpenSolaris 2008.11 and Red Hat Linux AS 5 (32 and 64 bit), and runtime support of IBM AIX 5L 5.3 (64-bit OS, 32-bit JVM). In addition, NetBeans IDE 6.5 and GlassFish Enterprise Server 2.1 are also now supported.

To see how this fits in with the broader picture of GlassFish OpenESB support, take a look at GlassFish ESB Supported Operating Systems and External Systems. There you'll see that GlassFish ESB supports multiple versions of Solaris and OpenSolaris, Microsoft Windows, Red Hat, and Mac. That's quite a list. I know from experience that supporting that range of platforms for an enterprise level application is no small feat.

The other big addition provided by Version 2.1 is support for GlassFish clustering in all components. This is a critical enhancement, because if a few components cannot be properly scaled, then those components can become bottlenecks blocking true scalability for the entire application. It's of no use to add new servers if processing is blocked by an unscalable, or insufficiently scalable, component that is widely used in your particular operating environment. This is no longer a problem in GlassFish ESB 2.1.

See the Release Notes for the other new and improved items, and visit the OpenESB home page for additional OpenESB-specific information.

In Java Today, Frank Kieviet reports GlassFish ESB v2.1 released: "After a few months of development, bug fixing, testing, etc, GlassFish ESB v2.1 is now released. New in this release is that is a lot easier to scale GlassFish ESB through clustering. All components now have support for clustering. By the way, GlassFish ESB clustering is (of course) based on GlassFish clustering. Also new in this release is the inclusion of the IEP SE and Scheduler BC (a new component!), several component enhancements, and support for AIX 5.3..."

Now available via Software Update and Apple's download page, the Java for Mac OS X 10.5 Update 4 and Java for Mac OS X 10.4, Release 9 promise "delivers improved reliability, security and compatibility for J2SE 5.0 and J2SE 1.4.2", and for Java SE 6 on 64-bit Intel Macs running Leopard. Apple's statement does not detail the security fixes, but a Mac Rumors article claims that the updates "address several vulnerabilities that could allow maliciously crafted Java applets to gain elevated privileges leading to arbitrary code execution," specifically citing Landon Fuller's public proof of concept exploit.

In the Forums, seik asks about an animation problem: "hello guys! seik is here with new questions for you!(again...T_T) I'm making an app to show videos. If it was only to play and stop it would be great but NOOOO, we need to make it more complete.....(for boss hapiness and my despair lol) So after a lot of study and pratice (....2 days is alot to me) I finally was able to make the bar that shows the progress of the video ^^.....with a small problem.....it only updates itself when I change focus on the form....T_T. Finally, after lots of useless talk, HERE IS THE QUESTION: How can I animate a component "all the time" instand of "only when I change focus". I mean: I want it(the bar) to repaint always (it could be every 1 sec or so), without the need for the user(who would be watching the video) to press a button(to change focus/update the bar)... "

kschaefe is Tackling 1.6 Sorting and Filtering in SwingX: "I wanted to start a thread to collect all of the places that we have 1.6 sorting/filtering code ideas. I have added some tasks to the Issue Tracker for migrating our codebase to be in line with 1.6. So, what are the ideas that we have? I think we could leverage a lot of the core code and make the RowSorter usable by JXList (more easily) by integrating ComponentAdapter with ModelWrapper. This would allow us to insert our code at the correct point by subclassing the DefaultRowSorter and ignoring the TableRowSorter. JTable is missing a key method createDefaultRowSorter because we're going to need to override several methods if we want to use a custom sorter as SwingX default. Anyway, what approach do we want to take to tackle this migration?"

And gw1921 provides a Tip to make LWUIT paint/display/scroll lists faster: "Hi all, I'd like to share an optimization tip with I used to make my lists scroll at least 50 times faster (literally) than they did, which was especially noticeable on Blackberry Storm, HTC etc etc where tap-flicking was terribly slow. My List(s) had excessive use of labels and images and so the list would take literally a second or two to change focus and to scroll. After a bit of profiling I noticed LWUIT was spending most of its time in Font.stringWidth, wasting precious cpu cycles on basically the same strings again and again (with a new repaint after every scroll-step/focus change). The solution was to subclass Font, add a 'String Width Pool' that keeps track of, say, 30 strings at most and their widths. You then use this cache to return width of strings you're already aware of... "

QuickCheck for Java Generates Data for Automated Software Testing

QuickCheck for Java is an automated software testing tool that tests programs by generating specified randomized input data sets and running them through the application. The software applies the techniques implemented in the Haskell QuickCheck tool to Java applications. QuickCheck for Java Version 0.4 was recently released.

QuickCheck is a lightweight specification based test tool. Each specification is tested with generated test cases.

Basically quickcheck is about generators of data. (The QuickCheck.forAll method is just a fancy for loop implementation.) Quickcheck can help in scenarios where whole classes of test cases have to be tested and it is not feasible to write tests for all distinct test scenarios. (E.g.: "This algorithm has to work for unicode string values of unlimited size.")

Version 0.4 enhancements include:

annotation-based characteristic definition for junit4
new CombinedGenerator generators: - int[]; set; sortedLists; non-empty list; lists(Generator integers, int lo); lists(Generator integers, int lo, int high)
new PrimitiveGenerator generators: dates(TimeUnit precision); dates(long low, long high); strings(maxSize); integers(int low); positive integer; positive long generator

The value of QuickTest is that it enables you to automate testing of systems using the full variety of input data that the application may encounter when it goes operational. I have done lots of work on complex automated data analysis systems, and testing the systems in advance of their becoming operational is difficult. Manually generating input data takes time. A tool like QuickCheck automates this, and enables exercising the software over a wide set of data conditions. Hence, it allows you to find situations where an particular set of input data causes problems. Once these conditions are found, you can correct the software such that it reacts in an appropriate manner, thus avoiding the undesirable situation of the software failing once it becomes operational.

The QuickCheck project has a To-Do List for the upcoming Version 0.5 and beyond. The project is seeking help with these items, as well as with the development of sample code and documentation. If you'd like to help, visit the QuickCheck for Java home page, scroll down to the bottom, and get in contact with the development team.

In Java Today, Thomas Jung announces Quickcheck for Java Release 0.4 is now available: " We would like to announce release 0.4 of QuickCheck for Java (quickcheck.dev.java.net), a implementation of QuickCheck with major enhancements (distribution functions, generator strategies, rerun of failed test instances, deterministic generators). Quickcheck supports Specification-Driven Development (SDD), which is a recent attempt to address some limitations of TDD by raising the level of abstraction. Like TDD, SDD is an incremental process that proceeds from failing specifications to passing code, and emphasizes short cycle time comparable to TDD."

The java.net JUGs project invites Java User Groups worldwide to enter their information so they can be included in the worldwide JUGs map, which shows the geographic location, leaders, and web site information for JUGs from around the world. It's fairly simple to add your JUG to the map. The current map itself is quite impressive. But, surely there are JUGs that are not represented. It's difficult to believe, for example, that there are no JUGs in Japan. Only one in China? Just two in India? None in South Korea, South Africa, or Mexico? If you're a member of a JUG that's not on the map, please take a few moments to add your JUG to the map.

And Gavin King reports JSR-299 Proposed Final Draft submitted: "I just submitted the Proposed Final Draft of JSR-299, Contexts and Dependency Injection, to the JCP. Download it here[1].

I'm using Metro 1.5 which claims interoperability with .NET 3.0 although I'm not exactly certain what that means since I haven't seen any examples or materials that show this working. I'm particularly interested in getting a C# client to deal with a Saml Sender Vouches secured web service does anyone know of any good resources or examples along these lines? ..."

Barry van Someren is working on Clustered setup (think Cloud) Glassfish v2 or v3?: "All, I've been using Glassfish for a few years now and am a strong believer in it's capabilities and stability along with Sun Web server 7. My experiences have mostly been with single server setups. Lately I've been working on setting up Java based hosting and I'm looking for some opinions. My hosting setup is based on a combination of Cloud Nodes (much like EC2 only with both monthly and hourly options) and physical hardware (for MySQL databases, since running these of a shared SAN is a bad idea) I was thinking that Glassfish is moving more and more into the direction of being an excellent cloud based hosting environment..."

And sbeard has a problem with Glassfish Message broker shutting down unexpectedly on its own: "We are running Glassfish Enterprise Server 2.1 on SUSE Linux 10.1. In Glassfish I created a standalone remote broker so that all applications would have a common broker to use for JMS and not the broker it creates with each standalone server you create. This way the starting and stopping the broker is independent of starting/stopping the standalone server and every standalone server has the same remote broker to use. So I have the Java Message Service settings in each standalone server configured to connect to this broker in remote mode. I created the remote broker this way... "

Java NIO.2 File System (JSR 203) Update

This week's java.net Spotlight highlights the Sun Developer Network article "The Java NIO.2 File System in JDK 7", ("NIO" = "New I/O") by Janice J. Heiss and Sharon Zakhour. The Java NIO.2 file system is an OpenJDK implementation of JSR 203. While the JCP currently lists JSR 203 as "inactive", work on the JSR is actually ongoing, under the leadership of Sun's Alan Bateman.

Janice and Sharon define the JSR's "three primary elements that offer new input/output (I/O) APIs for the Java platform:"

An extensive File I/O API system addresses feature requests that developers have sought since the inception of the JDK.
A socket channel API addresses multicasting, socket binding associated with channels, and related issues.
An asynchronous I/O API enables mapping to I/O facilities, completion ports, and various I/O event port mechanisms to enhance scalability.

Their article focuses on the first of these.

One might wonder: why, at this late point in the Java's history, are enhancements to something as fundamental as I/O needed? Janice and Sharon explain:

The Java I/O File API, as it was originally created, presented challenges for developers. It was not initially written to be extended. Many of the methods were created without exceptions, so they failed to throw I/O exceptions, which resulted in considerable frustration for developers. Applications often failed during file deletion, leaving developers confused as to why no useful error message had been generated. The rename method behaved inconsistently across volumes and file systems: Some were easily renamed, but others were not. Methods for gaining simultaneous metadata about files were inefficient. And developers wanted greater access to metadata such as file permissions, as well as more efficient file copy support and file change notification.

Developers also requested the ability to develop their own file system implementations by, for example, keeping a pseudofile system in memory, or by formatting files as zip files.

From this, it's easy to understand the reaction NIO.2 evokes from many developers: statements such as "we've needed this for a long time" and "finally!" In part, it's understandable that extensions to an I/O API will be required, as new types of file systems come into existence. It's a bit more surprising that the original I/O File API was designed without adequate exceptions handling. So, the frustation of developers, and their anticipation of NIO.2, is very much understandable.

"The Java NIO.2 File System in JDK 7" provides overviews of several areas where the NIO.2 APIs will improve the JDK's I/O capabilities:

As Alan Bateman says, in the conclusion of the article:

The file system API will be a significant boon to applications that today are forced to resort to native code to do many basic file system operations. Finally, the platform has support for copying and moving files, symbolic links, and file permissions, and for many other basic features whose previous absence inhibited effective access to the file system.

In Java Today, we note that development of the Genesis project continues to proceed at a rapid pace. The project had more commits than any other java.net project in May: "genesis is an open-source framework that aims to bring simplicity and productivity to enterprise application development, ensuring scalability, robustness and testability of your software. The main goal is to simplify the development of business components and the construction of complex graphical interfaces with minimum effort for developers. To accomplish its mission, genesis combines several open-source frameworks in a completely transparent way for developers, through the use of AOP (Aspect Oriented Programming)." The project recently released Genesis Version 3.2.

Manik Surtani announces that Infinispan Alpha 5 is now available: "Infinispan is an extremely scalable, highly available data grid platform - 100% open source, and written in Java. The purpose of Infinispan is to expose a data structure that is highly concurrent, designed ground-up to make the most of modern multi-processor/multi-core architectures while at the same time providing distributed cache capabilities. At its core Infinispan exposes a JSR-107 (JCACHE) compatible Cache interface (which in turn extends java.util.Map). It is also optionally is backed by a peer-to-peer network architecture to distribute state efficiently around a data grid..."

Kind of a windows service where some java code would be running in the background. This is not a web application; but we would use web services to let the clients (webstart swing app) communicate with the server. Would Glassfish or another module of another application server do the job ? There are so much sub projects on these technologies that I'm not sure where to start !!"
