Interface BpelEngine

All Superinterfaces:
Scheduler.JobProcessor
All Known Implementing Classes:
BpelEngineImpl

public interface BpelEngine
extends Scheduler.JobProcessor

Interface exposing the BPEL "engine". Basically, this interface facilitates dropping off events for processing by the engine. It is expected that all of the methods of this interface are called only from a "transactional context" (i.e. a transaction is associated with the thread invoking the method). The exact nature of the transactional context is not specified, however it must be the same context that is used by the BPEL DAO layer implementation. If a method invoked from this interface throws an exception of any kind, then the current transaction must be rolled back.
