4.9. Fault, Compensation, Termination and Event Handlers

Table 4.9. Fault, Compensation, Termination and Event Handlers

Name Description
Fault handler Executed when a fault is thrown by an activity.
Compensation handler Executed when the BPEL process encounters a Compensate or CompensateScope activity.
Termination handler Executed if a Scope is forced to terminate early.
Event handler Executed for events include the receipt of a message and a timer expiration.
Scope-level handlers A Scope may have any handler. Since Scopes can be nested, each level can define its own set of handlers. Events that are not caught and processed by a handler in an inner Scope, will be propagated to its ancestors.
Activity-level handlers Only the Invoke activity can define handlers. The handlers available to it are the fault and compensation handlers.
