Since the JSR-220 Expert Group introduced annotation-based dependency injection and the Java Persistence API as part of Java EE 1.5, it’s been possible to inject an EntityManager or EntityManagerFactory into most Java EE components using the dedicated @PersistenceContext and @PersistenceUnit annotations respectively.
Later, my JSR-299 Expert Group introduced a completely new approach to dependency injection, which ultimately came to be named Contexts and Dependency Injection for Java. Initially very controversial, CDI has over time become central to the Java EE platform—oops, I mean, Jakarta EE—and other technologies have adopted CDI, now in its sixth revision, as the base-level component model.
But back in CDI 1.0, I needed a way to bridge the gap between @PersistenceContext and the @Inject annotation supported by CDI.
And with CDI itself mired in FUD, I wasn’t exactly in a very strong political position to go asking the EE platform group to redefine their, at the time, pretty much brand-new dependency injection annotations in terms of the crazy new direction we were taking with CDI.
I'm pleased to say that CDI 1.1 is available and included in Java EE 7. If you want to learn more, read on, and join a webcast 12th June about all the technologies in Java EE 7. Both webcasts are followed by a Q&A session, when CDI experts will be on hand to answer your questions. The webcast is at [9 am PT / 12 pm ET / 5 pm London] or [9 pm PT / 12 am ET (Thursday) / 2 pm Sydney (Thursday)]
I'm pleased to announce the release of PicketLink 2.5.0.Beta3. This release is actually the successor to 3.0.0.Beta2 - we've changed the version number to help avoid confusion going forward, if you want the nitty gritty details about this decision then you can find out more below.
PicketLink 3.0 Alpha1 Released
I'm very pleased to announce the first alpha release of PicketLink 3.0. This release is the culmination of many months of effort by the JBoss Security team, with many contributions made from other project teams at JBoss and members of the community. I'd like to thank everyone involved with this release, from those who participated in the many design discussions on the security mailing list over the last few months, to those who contributed code and have started integrating PicketLink into their own projects.
Last week the JCP posted the CDI 1.1 public review draft. This draft continues to incrementally improve the 1.0 spec. We haven't added any major new features, instead we're concentrating on honing 1.0 :-)
Seam.Next Announcement
I’m very happy to announce the details for the first phase of our Seam.Next plan. I’d like to thank everyone for waiting patiently while we worked on this, and for providing feedback either directly via e-mail or IRC, or through the Seam forums. I’d also like to thank the module leads, key community members and other people that were involved in helping to shape this plan, it was very much a collaborative effort and we are very excited about the ideas and goals that were discussed and direction going forward.
Seam Spring 3.1.0.Alpha1 released
It took a while to release it (due to other work that needed to be completed first), and it took me a couple of weeks to announce it (i.e. until now), but my bit of news for today is this: the first release of our CDI Spring bridge, aka Seam Spring 3.1.0.Alpha1 is out.
My JavaOne 2011
It’s more than a week since I returned home from this year’s JavaOne, hence it’s probably high time I put down a few words on what was going on there.
