Method Detail

close

void close()
    throws WrongStateException,
           SystemException

The transaction has completed successfully. The participant previously informed the coordinator that it was ready to complete.

Throws:

WrongStateException

SystemException

cancel

void cancel()
     throws FaultedException,
            WrongStateException,
            SystemException

The transaction has cancelled, and the participant should undo any work. The participant cannot have informed the coordinator that it has completed.

Throws:

FaultedException

WrongStateException

SystemException

compensate

void compensate()
         throws FaultedException,
                WrongStateException,
                SystemException

The transaction has cancelled. The participant previously informed the coordinator that it had finished work but could compensate later if required, so it is now requested to do so.

Throws:

FaultedException - if the participant was unable to perform the required compensation action because of an unrecoverable error. The coordinator is notified of this fault and as a result will stop resending compensation requests.

SystemException - if the participant was unable to perform the required compensation action because of a transient fault. The coordinator is not notified of this fault so it will retry the compensate request after a suitable timeout.

WrongStateException

status

String status()
       throws SystemException

Returns:

the status value.

Throws:

SystemException

unknown

@Deprecated
void unknown()
                  throws SystemException

Deprecated.

If the participant enquires as to the status of the transaction it was registered with and that transaction is no longer available (has rolled back) then this operation will be invoked by the coordination service. This has been deprecated since the correct action when a GetStatus request fails is either to cancel or compensate the participant or to call error. GetStatus is only dispatched while the participant is completed so cancel will never be appropriate. compensate is called when the participant is unknown to the coordinator (it responds to the GetStatus request with an InvalidState fault). This will only happen if the coordinator crashed after the participant completed but before the client requested a close/cancel. error is called if any other fault response is received. So there is no other circumstance in which it would be appropriate for unknown to be called.

Throws:

SystemException

error

void error()
    throws SystemException

If the participant enquired as to the status of the transaction it was registered with and an unrecoverable error occurs then this operation will be invoked.

Throws:

SystemException
