Wolf, It looks like, when there are EJB3 beans involved, everything is processed by the EJB3 deployer. We actually tried migrating all the session beans to EJB3. It still fails, this time because it doesn't find the entity (2.1) beans. But we can't go on and migrate the entity beans to JPA, there's just too many of them. And in any case, we expected EJB 2.1 and 3 to be able to coexist. We'll wait for JBoss 5... Thanks for your time. Cheers!
