    NullPointer exception with CMP EJB

    Klaas van der Ploeg Newbie

      I'm trying to get a very simple entity bean to work on jboss 2.4.4.
      Deploying goes fine, but as soon as I call it's create method from the client, it fails with the following exception on JBoss (see below).
      It looks like a nullpointer exception in org.jboss.ejb.plugins.jaws.jdbc.JDBCCreateEntityCommand.execute but I'm not sure on that.
      Can anybody shine some light on this? Thanks!

      Klaas.
