i am not sure about JBoss2.4.4 but u should try out Jboss3.0.0beta. that definitely supports ejb2.0
jboss 2.4.4 supports part of the ejb 2.0 spec, however it doesn't support ejb cmp 2.0. That is only supported in jboss 3.0.
How about Local Interface? It would be nice if someone can list what EJB2.0 features are included in JBoss2.4.4?
environment interfaces are supported while relationships not.
With www.MVCSoft.com persistence manager You can extend jboss 2.4.4 to full ejb 2.0 compliance. A good choice, if You want use ejb 2.0 cmp today in a production environment.
