Method Detail

rollback

public void rollback(BitronixTransaction transaction,
                     java.util.List<XAResourceHolderState> interestedResources)
              throws javax.transaction.HeuristicMixedException,
                     javax.transaction.HeuristicCommitException,
                     BitronixSystemException

Rollback the current XA transaction. Transaction will not timeout while changing status but rather by some extra logic that will manually throw the exception after doing as much cleanup as possible.

Parameters:

transaction - the transaction to rollback.

interestedResources - resources that should be rolled back.

Throws:

javax.transaction.HeuristicCommitException - when all resources committed instead.

javax.transaction.HeuristicMixedException - when some resources committed and some rolled back.

BitronixSystemException - when an internal error occured.
