The Java EE 6 platform, along with Contexts and Dependency Injection, Bean Validation, EJB 3.1, JPA 2 and Servlet 3 have just been approved by the JCP EC. This completely changes the landscape for people developing web and enterprise applications in Java. There's just so much to digest here, and so many problems that are finally solved. EE 6 is something of a new start, and the beginning of a whole new ecosystem. Congratulations!
IntelliJ now has support for the new JPA 2.0 typesafe query facility I've been blogging about. It's very important that this stuff works smoothly with tooling, so it's great to see that the tooling vendors are on this early.
Ideas for next release of CDI
Q&A on InfoQ
InfoQ has published a their questions and my answers about CDI and Weld.

A developer new to Java EE posted in the Weld forum asking for advice on getting started learning EE 6. I've decided to promote part of my response in the forum to the blog.
Another nice portable extension
Here's a CDI portable extension that reads values from properties files and configures fields of Java EE components. In Java EE 6, this works for any Java EE component supporting injection
, including servlets, EJBs, managed beans, interceptors and more.
CDI Portable extension examples
One of the nicest features of CDI is the portable extension SPI. According to the spec:
Andy Schwartz's JSF2 summary
In case you're like me, and you missed this when it was first published, check out Andy Schwartz's summary of what's new in JSF2. (Andy's one of the good guys on the JSF EG.) It's fun to compare the final product to my wishlist from back in '07. Oh, what innocent, carefree days...
