Be looking sometime for the end of this year for an add-on pack version of Creator for the Netbeans 5.5 release.
Netbeans 5.5 beta info
http://www.netbeans.org/community/releases/55/index.html
General Java Enterprise Edition?5 platform support:
* Deploys to the Sun Java System Application Server PE 9 (Glassfish).
* Provides code completion and Javadoc for Java EE 5 APIs and deployment descriptors.
* Web tier technologies updated for Java EE 5 platform: Servlet 2.5, JavaServer?Pages 2.1, JavaServer?Faces 1.2
Does that cover it?
Please keep in mind that the Visual Web Pack that will be available for the NetBeans 5.5 release, IS NOT the full Sun Java Studio Creator product on Netbeans 5.5.
It is an introduction of the Visual Web application development capabilities, that Java Studio Creator customers have come to love, into the Netbeans community. It's a start towards the goal of providing the same functionality in both a Standalone, integrated, onestop tool, and as an Add-On to Netbeans.
As for when the Java Studio Creator product itself will work with EJB 3 and Java EE 5, you should be looking for something possibly around JavaOne next year. The roadmap is not set in stone yet, so things may move around some as they get more solid.
