The first morning of JavaOne was a great serendipitous event. How often does something fall into place like this: I saw Barton George, who looks after Sun’s relationships with Linux communities, and we decided to cook up a podcast about OpenJDK 6 in Fedora 9. As we walked to the recording room, I commented that it would be great if we could get Tom Fitzsimmons, too. Not two beats later, we rounded a corner, and there stood Tom with Patrick Macdonald. Of course they were available and happy to record with us, and away we went.
Hear Barton (and a little bit of me) interview Tom and Patrick about the journey of OpenJDK and IcedTea: OGG and MP3

This remaining 4% was filled with components from GNU Classpath by the IcedTea team. The term “IcedTea” came from the package name used because, at that time, Fedora didn’t have a trademark license to use “OpenJDK”. Of the GNU Classpath code used, some if it ended up completing the circle to be included in OpenJDK. Based on relationships made at FOSDEM 2007, the team from Fedora/Red Hat were able to work with folks from Sun and other places to do work in the community in advance of resolving the remaining 4%, and do it in a way that could be more easily folded into OpenJDK. What is riveting about this story is the speed and quality of the outcome that is clearly due to the open source methodology used. By opening all the code that they could, Sun made it possible for others to fill the gaps Sun could not immediately fill. By working closely throughout that process, all of the open source code was used and tested in the community. Sun had time to choose the right license so the code could be merged. If Sun had waited until they could open all the code, we would have lost an entire year of development (at least.) Now that OpenJDK 6 is available in EPEL 5 for Red Hat Enterprise Linux 5, it is only a matter of time before it gets certified to appear in an update. This is being worked on by Keith Seitz and Mark Wielaard, who have “not many” test suites to complete to be ready to pass the TCK. Once that is done, the implementation can be called “Java compliant”, which is an important step to being ready for an Enterprise Linux 5.x update. Listen to the audio to get all the details, and check out Barton’s blog entry for his viewpoint.
At the JBoss booth at JavaOne 2008, I spoke with RichFaces developer Alexander Smirnov (OGG, MP3.) Alexander is the founder of the Ajax4jsf project, which he started as a personal side effort. It grew out of his interest in JSF and was originally run as a stand alone, self-hosted project.
As he developed Ajax4jsf, Alexander began working with the MyFaces community, and started communicating more with the larger JSF community. He moved the project to SourceForge at the suggestion of RichFaces lead developer Sergey Smirnov (no relation.) Exadel began developing the RichFaces JSF components library and Alexander joined the project as a framework background developer.
At the time it moved to java.net, Ajax4jsf had grown more useful when integrated with the RichFaces component library. RichFaces, however, was still not open source. The combined projects came to the attention of JBoss, which contracted with Exadel to open source both projects as JBoss projects. These were recently combined into a single project under the RichFaces name, available through JBoss.org. (RichFaces is combined with the JBoss Tools Eclipse-based developer environment to make up the JBoss Developer Studio subscription offering.)
Current activity for the RichFaces project includes a focus on building RichFaces functionality within JBoss Portlet Bridge. JBoss Portlet Bridge implements JSR-301 to provide support for not only JSF running in a portal, but also Seam and RichFaces.
Joining forces with JBoss has brought significantly more usage, ten times or more in terms of downloads. In particular, Alexander says there is an obvious increase in forum questions and discussions. In terms of attracting contributors, there are currently very few code contributions from the community outside of Exadel and JBoss. Alexander and Sergey describe the development process for the RichFaces team as being structured with a well-oiled process, which creates a higher barrier of entry for people outside of the team. As early ways to bring in external contributors, there are current needs for testing, defining future requirements, and requesting features and enhancements.
For the future roadmap of RichFaces, Alexander says that the next step is toward semantic web technologies.
This afternoon I caught a few minutes with Ivelin Ivanov, a lead developer on the Mobicents project. Mobicents is the first certified open source platform for developing and deploying JSLEE applications.
This audiocast is available from the JBoss.org podcast channel, in OGG and MP3 formats.
Continuing with the audiocast series from JBoss World 2008, this is EJB3 lead developer Carlo de Wolf talking about EJB 3 for Java developers new to Enterprise JavaBeans. The audio is available in OGG Vorbis and MP3 formats. Slides from the presentation are available.
As an ongoing joint operation, this audiocast is the first that is fed into the JBoss.org podcast channel (ATOM feed.) This is fun, as it allows us to distribute not only a title and rich description, but a thumbnail image full of meaning:
Starting with this “Introduction to Seam” by Pete Muir from the 2008 Jboss World in Orlando, JBoss.org and Dev Fu are presenting original audiocasts of technical presentations from various JBoss events and presentations.
The audiocast is available in MP3 and OGG Vorbis formats. You can follow along with Pete’s presentation slides. This introduction is intended for Java developers and anyone interested in learning more about what Seam is, how it got this way, and where it is going next
This audiocast is the first of many, to be released one or two a week as we get through the editing process. That should carry us right up to the Red Hat Summit, where we seek additional relevant and interesting developer audio content.
