JBoss 4.0.4-GA (I believe) shipped w/ EJB3 RC7, and 4.0.5 has RC9. I'd recommend wither upgrading JBoss AS using the visual installer, and selecting the "EJB3" profile, or patching your existing by obtaining only EJB3 RC9 (current release). That should have a patch installer in it to give you what you need. S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3994076#...
