I just wanted to confirm you were not using one. anonymous wrote : m_metaAgent = (MetaAgent) PortableRemoteObject.narrow(ref, MetaAgent.class); In EJB3, you no longer need the PortableRemoteObject.narrow. You can directly cast the returned object to the remote interface: MetaAgent metaAgent = (MetaAgent) jndiContext.lookup("MetaAgentImpl"); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4051871#...
