Hi all,
What is the answer for the fourth scenario

The exception for when the client starts a transaction, and the Container has to roll it back.


At first I thought it was TransactionRolledbackException/TransactionRolledBackLocalException but I'm a little confused as to when that exception would be thrown. It also could be any runtime exception, because they always cause the Container to rollback a transaction.
Can someone please clear up my confusion.
Much appreciated.

Hi Keith,
TransactionRolledbackException/TransactionRolledBackLocalException both are system exception (RemoteException for remote clients / EJBException for local ones). So it's not contradictory with what you write: if a RuntimeException is thrown, the container will rollback the transaction and, in case the client started the transaction, will then throw TransactionRolledbackException or TransactionRolledBackLocalException which are just more specialized system exceptions.
Best,
Phil.
