[jboss-user] [JBoss Portal] - ClassCastException accessing EJB3 from portlet

Hi all, I posted this to the EJB3 forum originally, but just tested my app using a plain WAR file and it works fine, so I think it is something related to classloading and my portlet... I'm trying to use my EJB3 application from a JBoss Portal portlet and getting the infamous ClassCastException. I have read all the wiki & other resources on classloading, etc, but have not been able to solve this one. Specifics are: JBoss 4.0.4GA, Portal 2.4-CR2, EJB3 RC8. I have packaged the ejb3 application and the portlet application in separate ear files (originally tried using just a war for the portlet), and have also tried scoped loader repositories. The portlet includes a jar file of only the client parts of my ejb3 application. I have JBossAS configured for call by value, etc. Here are application specifics: ClientEJB is an entity that implements Client interface ClientSessionBean is a SLSB ClientSessionLocal is the local interface to the session bean The method I am calling on the session bean is: Client createClient(String username, String password) It creates an instance of ClientEJB, persists it, and returns it as a Client interface. The call to the session bean works fine. I get the CCE when I try to use the returned object as a Client and not a ClientEJB. What should I be doing to make this work? Hopefully somebody already ran into this scenario and can help. Let me know if you need more information. Thank you in advance, Gary.
