    Getting Remote &EJBException Eventhough classpath, XMLs, properly defined

    814809
      Hi,
      I am having bad time debugging with this problem. I am migrating my codes from Java 1.4 to JDK 6 and Weblogic 8.1.5 to Weblogic 10.3. I have converted the deployment descriptors of EJBs using DDConverver utility of weblogic. Beans consists of stateless session and Entity beans (2.1). Application is made of JSP as front-end and EJBs as middle ware. While logging i am calling one session bean which internally called entity beans and loads the same. I am getting following exception when Session bean calls entity bean. Session call is successful, only the issue is entity call from session bean. I have attached the details of the beans in the attachement for your reference.

      I am using development environment for this. JSPs are stored at
      C:\MisasiaAppln10.3_DEV\misasia\autodeploy\misasia
      EJBs are deployed at
      C:\MisasiaAppln10.3_DEV\misasia\servers\AdminServer\upload

      Exception Details:
      java.rmi.RemoteException: EJB Exception: ; nested exception is:

      Sample Codes:

      Call of Session from JSP (THIS WORKS FINE)
      env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
      env.put(Context.PROVIDER_URL, "t3://localhost:7001");
      ic = new InitialContext(env);
      ctrlHome = (controlHome)ic.lookup("controlSessionEJB");
      ctrl = (control)ctrlHome.create();

      Call of Entity from Session (THIS FAILS)
      Object refsetup = ic.lookup("java:comp/env/ejb/SetupMasterEJB");
      // This is the line which gives an error
      SetupMasterHome setuph = (SetupMasterHome)PortableRemoteObject.narrow(refsetup, SetupMasterHome.class);

      Please help me to get rid of this exception.
