    Problem with JBoss Scheduler. Please help me!!!

    Fabrizio Variano Newbie

      Hi.
      I have a problem with the JBoss scheduler.
      I follow these phases:
      1- Create a session bean that implements Schedulable.
      2- Implement the method "perform" and put there the code to be executed by Scheduler
      3- Create a jboss-service.xml and put this file in a sar file.

      Then during of deploy return me this error:

      ERROR [Scheduler$Listener] Handling a Scheduler call failed
      java.lang.NullPointerException
