    NPE when deploying EJBs

    ludovicc Mar 24, 2004 4:05 AM

      Hello,

      I've got an NPE while deploying my EJBs, and i can't locate the problems as i don't use load groups in my CMPs. The deployment descriptor is generated by XDoclet 1.2, and it doesn't contain any reference to a load group.

      Thanks for your help,
      Ludovic

              How many EJBs are you deploying at once? This problem will be much easier to solve if you just look at deploying one EJB.

              If you have got it down to just one EJB that is causing the error can you provide the generated deployment descriptors, looking at previous posts it is probably a missing element required for entity beans.
