public class RollbackException

extends Exception

The RollbackException exception indicates that either the transaction has been rolled back or an operation cannot complete because the transaction is marked for rollback only.

It is thrown under two circumstances:

• At transaction commit time, if the transaction has been marked for rollback only. In this case, the commit method will roll back the transaction and throw this exception to indicate that the transaction could not be committed.
• At other times, if an operation cannot be completed because the transaction is marked for rollback only. The enlistResource and registerSynchronization methods in the Transaction interface throw this exception to indicate that the operation cannot be completed because the transaction is marked for rollback only. In this case, the state of the transaction remains unchanged.
