    ejbPassivate() and private transient fields

    Frederic Burlet Newbie

      Hi,

      I have a stateful session bean that has a private transient field which is the LocalHome interface of another session Bean (a stateless one).

      I instanciate a proxy by invoking a private method from within the stateful session bean as in the following extract:

      private transient MySessionBeanLocalHome privateField;
      ...
      private MySessionBeanLocalHome getMySessionBeanLocalHome() {
       if (privateField == null) {
       privateField = MySessionBeanUtil.getLocalHome();
       }
       return privateField;
      }
      


      In the ejbPassivate() method of the stateful session bean, I call the getMySessionBeanLocalHome() private method and I get a ClassCastException when the session bean passivate (here below the stacktrace I get).

      I don't understand what happens. Any idea ?

      The stacktrace:
      12:26:10,922 ERROR [synch.driver.ScannerSynchSessionBean] [801018530188-K / 32000110] Could not passivate
