    MessageFormatException

    delboypass Newbie

      Can somebody please tell me why this is going wrong?
      Ive had a look around and sometimes my code works but then sometimes it does this. Does this error have anything to do with the serialVersionUID and can somebody tell me what a serialVersionUID is?

      javax.jms.MessageFormatException: IOException: com.btexact.erica.billing.EUBillingEvent; Local class not compatible: stream classdesc serialVersionUID=-58111460479134682 local class serialVersionUID=-5214677529919586059

      The simple piece of code that can regenerate this error is:

      if (message instanceof ObjectMessage)
      {
      System.out.println("Message is instance of object message");
      ObjectMessage msg = (ObjectMessage)message;
      objecttype = msg.getObject();
      }

      Any help???
