In Relation To

Andy Gibson has written a nice tutorial to help you get started with JSF 2 and CDI using Netbeans and Glassfish. It's great to see that both Netbeans and Intellij 9 already have excellent support for Java EE 6.

As I'm sure you've all seen, Java EE 6 has gone final. You can now download the Final Release of the Contexts and Dependency Injection, Bean Validation, Java Persistence API 2 and Java Servlet 3 specifications from jcp.org, and read the linked javadoc for the entire platform. It's also a good chance to check out the Java API for RESTful Web Services specification, which now includes CDI integration, if you havn't already.

Matt Corey has blogged about CDI interceptor bindings, showing a simple example of how you can implement your own @RequiredTx annotation. He also lightly criticizes the use of beans.xml for interceptor enablement. (This was also discussed in the Weld forum.) I really think we have the design just right here, and I'll explain why. But first let me remember why CDI interceptor bindings are much better than the @Interceptors annotation from EJB 3.0.

I've seen a couple of folks wondering why CDI requires a beans.xml file in every bean archive. If there's no alternatives, interceptors, or decorators to declare, why do you need to have the empty file?

DZone recently interviewed me about CDI and Weld. Please, no more jokes about the hat. I had a horrid morning that day and had to run off to the interview without a shower, breakfast or coffee.

I called EE 6 the beginning of a whole new ecosystem. Some of you guys are probably thinking this is hyperbole. Well, here's why I think it's possible.
