    NullPointerException in UnicastServerRef dispatch method

    eldiosyeldiablo Newbie

      I am getting a null pointer exception that I cannot figure out where it is coming from or what is wrong.

      My unit test run fine but for some reason when I use my same connection classes inside another program I am getting this.

      I have placed both my RMI client and my JBoss EJB session bean in debug mode and the call never gets into my EJB session bean. The client's request looks fine.

      Thank you very much,
      David
