anonymous wrote : The EJB 3 deployer in AS 4.2 can only deploy EJB 2.1 session beans. 2.1 Entity BMP/CMP beans are not deployable. OK, this explains the problem. I had no EJB 2.1 sessions, only entities in the module. Is there somewhere documentation about AS 4.2 EJB 3 capabilities. I tried to look, but did not find anything comprehensive in any obvious place (which would be the Documentation link for AS project -- there does not appear to be any documentation for 4.2). JBoss EJB3 project has the reference document, but that's not very helpful either, as far as I can see. Is there going to be any change to this in AS 4.2 series? What about AS version 5?
