Hi!
I have the following stateful bean:
|
| public class MyStatefulBean implements MyStatefulBeanI,
SessionSynchronization {
|
| @PersistenceUnit(unitName = "db")
| public EntityManagerFactory factory;
|
| public MyEntity getObject( int id ) throws Exception {
| EntityManager m = factory.createEntityManager();
| return m.find(MyEntity.class, id);
| }
|
| @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
| public MyEntity update( MyEntity newEntity ) throws Exception {
| EntityManager m = factory.createEntityManager();
| oldEntity e = m.find(MyEntity.class, id);
|
| e.setAttribute1( newEntity.getAttribute1() );
| ...
| ...
| m.flush();
| m.clear();
| m.close();
| }
|
| public void afterCompletion(boolean flag) throws EJBException,
RemoteException {
| if( flag == true ) {
| sendJMSMessage()
| }
| }
|
| .....
|
| }
|
|
As far as I understood, after update() it is not guaranteed, that the data is
in database and commit event already happened. So, as I have the fat clients it
can be the case, that after update() was called, getObject() still returns the
old entity.
My question is - is it guarateed, that after the afterCompletion() method the
database commit already happened, and it is safe to call getObject() to receive
the new data?
Thank you,
Konstantin
