    EJB3 access issue between portal 2.7.2 and AS 5.1.0GA

    gunther verhemeldonck Newbie

      I've deployed an EJB3 service on JBoss AS 5.1.0.GA. I now want to interact with this service from portlets deployed on JBoss Portal 2.7.2 (on JBoss AS 4.2.3). For some reason the remoting fails with a NullPointerException.

      Caused by: java.lang.NullPointerException

      Is this a bug or is there an incompatibility between version 4.2.3 and 5.1.0.GA? Should I instead be running both servers on level 4.2.3? Maybe this is a classloading issue, since I can access the service from a CLI environment without a problem.

      Thank you
