Java User Groups

40+ Java User Groups from 6 continents have participated in WildFly 8 Launch so far, and a few more are still lined up. This has truly been a global participation so far, and truly reflects the spirit of Java community. Several of these were delivered virtually primarily using G+ hangout, and then some in person during the travel by WildFly team. Lots of interesting conversations and feedback...

This entry lists Ed’s picks for the brand new JavaLand conference. Many of the talks are in German, but there is enough English to make it worth your time. It looks like there is a lot more English content in day two. Also, the conference was endorsed by java.net editor Kevin Farnham in his blog post from Saturday, 1 March 2014. Monday 25 March 2014 Welcome and Keynote, Fried Saacke,...

Java Enterprise

While parts of the cloud IT that are still being hyped are changing rapidly, the whole segment is not past the hype yet. The cloud report [1] that Gartner published 9 months ago still holds true today. Reports of disillusioned customers of such solutions [2][3] are a clear sign that the hype might have reached its peak for most parts of cloud offerings, though. And while many articles discuss the...

I presented this demo at DevNexus 2014 in Atlanta today. It is Reza's demo with just a pinch more Java EE thrown in. This blog entry covers how to fully internationalize an AngularJS application with just a pinch of Java EE. Reza hosts the code for this demo on his github. The demo has a chat client and a todo list. This blog entry only looks at the chat client, and assumes basic familiarity...

I've been blessed with the opportunity to speak at DevNexus 2014. This is my first time speaking at a DevNexus event and I'm excited at the opportunity to meet and learn from many top-name speakers currently practicing today. As I planned out my time here are the sessions I've added to my calendar. Day 1: Monday 24 February 09:00 Welcome and Sven Peters Keynote, Hall A From the buzz around...

This blog entry describes an unsupported process for overwriting the version of Mojarra that comes bundled in WLS 12.1.2 and beyond with an arbitrary version (from groupId org.glassfish artifactId javax.faces). Sometimes it is necessary to upgrade the version of Mojarra that comes bundled in WebLogic Server with a different version, either newer or older. One such usage: the Mojarra team at...

In every JSF application view state is kept either on the client or on the server. How do you make sure this state is smaller? The 'com.sun.faces.compressViewState' comes in handy here. It makes it so that the Mojarra runtime will Gzip compress the view state. Note the context-param is set by default to true, so only if you want to turn it off you will need to do something. In your web.xml file...

Today we are covering what the "com.sun.faces.sendPoweredByHeader" context-param does. Historically the JSF runtime would send the "X-Powered-By" servlet response header that would tell what the backing engine was (for Mojarra 2.2.x it would show "JSF/2.2"). To make it possible to turn this on or off this context-param was introduced. From a security perspective it would be smart to keep it off...

The "com.sun.faces.validateXml" context-param makes it possible for you to have the Mojarra JSF runtime verify your configuration files against the faces-config.xml schema. If an error is found you will immediately be made aware as deployment will fail until you fix the problem. Note when you are ready to go to production the "com.sun.faces.validateXml" context-param should be set to "false". In...

By convention in Faces Flows the page that is the start node has the same name as the flow, but is it possible to change that? It sure is, read on! We'll dive into the Faces configuration file that will make this work. <faces-config version="2.2"              xmlns="http://xmlns.jcp.org/xml/ns/javaee"...

The results of the most recently completed Java.net poll suggest that Java EE 7 is finding increasing use, impacting more projects and the daily work of more and more developers over time. This is one more indicator that the Java EE 7 release has to be considered a major success: the release occurred less than a year ago, yet the impact is already considerable. A total of 149 votes were cast...

The JavaEE team at Oracle has been busy processing the feedback from the JavaEE 8 Community Survey Question 6 in part one of the survey reads: "Is there any one de-facto standard technology in this space [Server side web MVC framework, aside from JSF] to which we should look for inspiration". For those respondents that answered yes to that question, fully half of them cited Spring MVC. By way...

Why would you add a placeholder component to the tree using ui:component? Well, sometimes you need to add content dynamically, but you also need to be able sure where it ends up. Why would you need to know where it ends up? Well imagine the following scenario   <ui:component id="component1">    <ui:include rendered="#{myBean.include1Yes}"...

Lets start with a small quiz: Can you find 3 differences in the pictures below? Yeah, you got it. That was an easy one. :) Surprisingly, implementing preview for extra asset types has been relatively simple as well. When coming up with the architecture of DAM, the Magnolia team chose to not generate previews and thumbnails of assets directly in the module, but rather delegate this functionality...

In the most recently completed Java.net poll, developers suggested that, yes, they're aware of "Big Data" and its implications, but overall they're not all that surprised at what they're seeing in that area. A plurality of votes went to "It was bound to happen, given today's powerful computers, it's no big surprise"... A total of 135 votes were cast in the poll. The exact question and results...

Java Web Services and XML

The most recently completed Java.net poll, which was submitted by Walter Nyland, asked the community about which technologies represent the future of the view layer in Java EE apps. A total of 245 votes were cast in the Java 8 poll, and two comments were posted. The exact question and results were: What's the future of the view layer in Java EE applications? 26% (64 votes) - Java EE...

It actually happened a few weeks ago already, but I simply didn't find the time to spread the word earlier -- just too much other stuff to do (see end of posting), so I tell you now: WebDAV Support for JAX-RS 1.2 is out! What has happened since 1.1? First of all, 1.2 is a complete internal overhaul, which not only finally is covered with unit tests rather completely (which revealed several...

Java Desktop

The Java is a platform which grown up quickly, for many rations such it can write once time and run anywhere, it runs languages on JVM. There is a myth that Java cannot compile its sources on run time, but it's truth? Have a dynamic language is important to make some projects, for example, calculate taxes to different cities, so the source should be on the database and each city it puts the...

JCP

This is my first blog on java.net! Happy new year! At 2014/01/11, A big Java EE 7 event has been held on China Nanjing Software Valley jointly organized by China (Nanjing) Software Valley Joint Management Committee and China Nanjing Java User Group. ChinaNanjingJUG(http://q.weibo.com/1696581) is founded at 2013, and focus on the promotion of Java EE and Java related technology into China....

Java Tools

An essential part of a well-written unit test is a well-written assertion. The assertion states the behavior you expect out of the system. It should tell you at a glance what a test is trying to demonstrate. It should be simple and obvious. You should not have to decipher conditional logic or sift through for loops to understand what it is doing. In addition, any non-trivial logic in a test case...
