    Repeated NPEs using SFSBs

    Daniel Cardin Newbie

      I have done some tests on clustering stateful beans and came accross the following exception, repeated over and over, when I tried removing the tutorial.jar file from the farm directory.

      Incidently, I had beans online when I did this, and a message appared on the other clustered server saying it was unable to delete the jar from the farm directory.

      so first, the exception and then a question

      5:09:09,015 ERROR [STDERR] java.lang.NullPointerException

      5:09:09,593 ERROR [STDERR] at java.util.TimerThread.run(Timer.java:462)


      The question is: What is the proper way to undeploy a jar accross a cluster using the farm directory.

      Thanks!
