Does JBoss need to be configured in order to use it? It's not used in EJB3 for JBoss. It's (probably is still) used for EJB2.x. The EJB3 interceptors are all present in ejb3-interceptors-aop.xml in the deploy folder. In JBoss AS-5, for EJB3 remote interfaces, the interceptors are smart enough to figure out whether the client lies in the same VM and if it does, then the call is *not* routed through any network layer. However the call for EJB3 remote interfaces, *is* still serialized/de-serialized (since the spec mandates it). Currently there's no way to disable this. I guess, you could probably add a feature request https://jira.jboss.org/jira/browse/EJBTHREE to allow something along those lines. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528878#528878
