Java Desktop

Last year, in JavaOne 2004 and in the brazilian event BrazilOne 2004 we presented a few multimedia JAVA projects. One of them was the RABISCO, a project from the Interdiciplinary Nucleous of Sound Study (NICS) of the State University of Campinas (UNICAMP). RABISCO is one among several other projects from the NICS about the research of virtual music instruments for cooperative playing and...

Normally I don't comment on new products, especially hotly anticipated ones that a million others will pontificate endlessly. However, I'm breaking my rule because I'm quite amazed by the new iPod Shuffle and iMac Mini. Not because of the products themselves but because of what they represent. They are both the triumph of software over hardware. the iPod Shuffle If you take an iPod Shuffle and...

It's true, it's true, it's finally here: the 2005 JavaOne Call For Papers. So now the big question is: what do we want to do with it? Here are 3 ideas to get you started, no matter who you are: Submit!: Got a great idea for a talk? Some nifty technology you'd like to describe in detail? Itching for the worldwide fame and fortune that speaking at JavaOne is sure to bring? Then bring it...

One of the traps to avoid when aging is regret; the more one accomplishes in life, the harder it can be not to regret some of your decisions along the way. Some days it seems life would be perfect if only we had the ability to "hit undo" on those mistakes. Life doesn't have such an undo facility, but happily we can easily code them into our applications. "Easily?", most developers might ask,...

Java Tools

Let's take two examples that are given in any AOP language, logging and context passing. AOP takes pride of the fact that it allows "injecting" code at the beginning and at the end of any method (specified using sophisticated "regular expressions"). But does this really qualify as a logging and tracing mechanism? Not really. Any non-academic application has functions with multiple exit points (...

Just as there is no one language that is universally suitable for every programming task, so is it in the world of software APIs. I have often found that one size does not fit all. Sometimes the task at hand may require an API that provides a high degree of flexibility, extensibility and/or transparency. Simplicity and a small footprint may be required on some other project. Yet another may...

Javapolis was clearly a great show to be at - I wish I'd had more time to see more of it, not to mention Antwerp in general. Also I finally met Vincent Brabant, who's been active in the NetBeans community for years and made the French localization of NetBeans happen. It's always nice to do a presentation where you have something to demo you know people will just love, and I had not one but...

Its official, Netbeans 4.0 is out. I'm probably one of the worst IDE users in the world, although the current crop of IDEs are so powerful that you don't need to look at the instructions :*). NB 4.0 worked out of the box and even I was able to add a little enum in the example. Total time taken for it to download install, do some analysis of my jar files and edit the example was just under 20...

Java Web Services and XML

Our group has two summer intern positions available, one to work with the new Fast Infoset project, the other to work with the new implementations of JAX-RPC and JAXB 2.0. I am looking for some strong candidates. The projects should be a lot of fun and I have had some very good experiences in the past; my only concern is that I blinked and didn't post this until now. Check out some of the...

Pierre is asking for ideas on what developers want to see in the Web Tier sessions at JavaOne this year. I'll add my plea to his, but on the Web Services, XML, et environs area. What Technical Sessions, BOFs or other activites would you want to see at JavaOne?

Here are some notes from a "brown bag" talk that I am preparing for our IT staff, many of whom are died-in-the-wool mainframe COBOL programmers. This talk will be far more evangelical then technical, and I hope that it will de-mystify SOA for some. I'm sure many of you will say "Duh!" when you read some of the points, but you'd be surprised how many folks just don't get it (yet). I like the...

Java Enterprise

There is always a great deal of interesting proposals submitted for the JavaOne conference, and this makes it really challenging for the various selection committees. In his blog last Monday, Casey Cameron provided good advice for submitters. In my case, I'd like to turn this around and ask potential conference goers for any advice they would like to give regarding the selection of the web-...

I am glad my original post about Practical AOP and Transparent Remoting has received polite and smart comments against it. This is definitely a nice way to get the discussion about AOP going! Here are my answers to these comments. First of all, cajo said that "this is a perfect example of why I fall into what you call your third AOP viewpoint. As you said, magic happens; but it is also totally...

There are basically four views about AOP nowadays (ok, it's more or less the same for any technology): those who think it's the golden hammer and everything is a nail, those who think it has some applicability, those who are strongly against it or have deep concerns about its wild adoption and those who simply couldn't care less about it. :-) I hope this kind of posts I intend to write help all...

Portlet

Although this month's tip is entitled, "Internalizing Your Portlets", you can use resource bundles for non-internalized portlets. Why would you want to? Well, for one, it would give you a central place to put all of your messages. Two, you can be assured that you don't have similar yet different messages in your application. If you say it one way in one part of the application, why not say it...

JXTA

The JuxTest team have published their recent findings. These folks are doing an amazing job. Truly amazing! There is nothing quite as motivating as working within a community where all the pieces fall into place. Mathieu and David have generated some sweet graphics measuring the recently released JXTA 2.3.2 with various configurations against past milestones. Metrics include: JXTA 2.3.x over...

Java User Groups

NetBeans really rocks. As many of you know, I am a long-time user of NetBeans, now. Already 4 years now that I am using NetBeans. Already 8 months that I was playing with the alpha, beta, RC1, RC2 of NetBeans 4.0. And yesterday, it was a big day: The official announcement of the NetBeans 4.0 release. The first time I met a NetBeans developer, after 4 years exchanging mails about NetBeans. When...

During the keynote of this morning, Someone of Sun (I am sorry, but I don't remember who) speaked about Java and Real Time Application. Java and Real Time Application ? Not possible, I though. You can't garantee Real Time when you use applications based upon JVM having a Garbage Collector that can suspend your thread at any moment, and for somes time (it may be short, but always too long for Real...

Yesterday morning, Javapolis began with a Key note of Rick Ross, the founder of http://www.javalobby.org. He explained why it's very important to have a strong and active java community. He said that we, as Java developper have to play an actor's role, and not be passive. Then, he does a little presentation of web sites that form the javalobby community. He also speaked about what he will set in...

Java Communications

He spoked about Java. But not about the Java Language itself. No. About the Java Virtual Machine. He explained that dynamic language like Perl, Python could accelerate the development, and also be robust. Then, he speak about Jython, that is running upon the Java Virtual Machine and could easily be connected with all the current Java APIs. So, could you imagine the advantage of a dynamic...
