[jboss-user] [EJB 3.0] - ClassCastException calling EJB3 from Portal

Hi all, 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 RC7 (I just noticed RC8 was released last week, so haven't tried it yet). I have packaged the ejb3 application and the portlet application in separate ear files, 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? I'm sure if I package it all in the same ear file it will work, but I don't want that (though I haven't tried that yet). Hopefully somebody already ran into this scenario and can help. Let me know if you need more information. Thank you in advance, Gary. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960986#...
