I wanted to let you know that we just released JAG 4.0 http://jag.sourceforge.net). JAG is a java application that creates complete, working J2EE applications based on a struts 1.1 web layer.
JAG has a pluggable business/persistence layer and adds support for EJB3 and Hibernate 2.1 in this release.
EJB3 is supported for the EJB3.0 Preview Release 2 of JBoss.
Since JAG also supports EJB2 using xdoclet, it's great to see how all xdoclet markup is obsolete for the EJB3 release now!
I hope you'll find it usefull.

cheers,

Rudie Ekkelenkamp.
