I'm a little confused... I've heard CMP 2.0 support _is_ partially supported in JBoss 2.4.3, but I can't get an abstract entity bean to deploy for the life of me. Please shed some light :)
Some parts of EJB 2.0 is supported in JBoss, but *not* CMP 2.0. The features of EJB 2.0 JBoss sports are local interfaces, message-driven beans and mdb.
