Exit
• Assists us to end the process
• Usually Exit is used to kill/exit a running BPEL process, which
is usually done when an exception occurs or data validation
fails for an activity within the BPEL process. For example, an
invalid order ID will make the BPEL terminate the activity and
will not proceed with order fulfillment activities. The Exit activ-
ity replaces the Terminate activity from BPEL 1.1
•
RepeatUntil
• Provides a mechanism to repeat the execution of a contained
activity until a given Boolean condition becomes true.
• The minimum execution value is one.
•
Compensate
• Assists us in implementing recovery business logic when it is
either partially or fully executed
• Compensate activity through compensation handlers allows
us to cancel or reverse a previously executed activity
• A compensation handler defines an undo sequence, for ex-
ample, cancel order
• Compensate activity can be invoked either from another com-
pensation handler or only from a fault handler
