    Self Relation

    Jens Newbie

      Hello everybody

      I am trying to deploy a Bean that has a One to Many relationship to itself and I get a
      java.lang.NullPointerException

      Is there something wrong with my ejb-jar.xml (I doubt that) or maybe still a Bug of jBoss 3.0 or even that self relations are not allowed?
      Any help is appreciated.
      Thanx, Jens
