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
