ejbPassivate() and private transient fields

[fburlet]

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
