Hi,
Can someone explain me why I have to add lines (1) and (2) in following snippet of code
Info
-----
jboss-server : 4.0.4
hibernate : 3.1.3
DB : Oracle8
EJB : SLSB
Transaction tx = null;
try {
Session session = factory.getCurrentSession();
tx = session.beginTransaction(); (1)
session.save(inputObject);
session.flush(); (2)
} catch (RuntimeException e) {
tx.rollback(); (1)
ExceptionHandler.analyze(log, e);
}
(1) I have to add this to catch PropertyValueExceptions (not-null constrain form hibernate)
(2) I have to flush to generate a ConstraintViolationException in case of saving the same inputObject.
If I don't add these lines, the exceptions are thrown by the container and catch by the
ejb-client as a RemoteException witch is very annoying.
Adding lines (1) and (2) prevent this and the exceptions are throw as applicationExceptions witch is OK.
But I don't quit understand what actually happens. I though that CMT/EJB was also taken care of the commit and rollback of the transaction ???
If you need additional info don't hesitate to reply.
Additional info :
Following hibernate properties are hard coded by the jboss-hibernate Mbean
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup
hibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory
hibernate.transaction.flush_before_completion=true
hibernate.transaction.auto_close_session=true
hibernate.connection.agressive_release=true
hibernate.connection.release_mode="after_statement"
Thanks
