I support a project that's deployed under JBoss 4x and it has a massive amount of EJBs. The EJBs are EJB 2.1 spec, mostly stateless with a few stateful. Our client wants to upgrade to latest Wildfly distro but ideally doesn't want to throw resources at converting EJB 2.1 to EJB 3 at this time. So the question is EJB 2.1 supported in Wildfly 8? Basically how backwards compatiable is the EJB container in Wildfly? I couldn't find anything in the docs.
