    NullPointer when invoking method on SessionBean

    Gert Konings Newbie

      I get a weird NullPointerException when i invoke a method pairHullATISCode on my StatefulSessionBean. When I invoke another method of this bean, all works fine. Strangly the only log of this error is the one below:

      ERROR [org.jboss.ejb.plugins.LogInterceptor] RuntimeException:
      java.lang.NullPointerException

      I'm using JBoss 3.2.1, most of the time I'm understand the exceptions that I cause, but the this makes me lose my hair.
