public abstract class AbstractExternalTransactionController

extends java.lang.Object

implements ExternalTransactionController

Purpose: Abstract implementation of an ExternalTransactionController.

Description: This class implements the registerSynchronizationListener method, satisfying the ExternalTransactionController interface. In order to interface to different transaction services (e.g. OMG OTS service, Java JTS service, etc), the registration of a synchronization object is done in the register method, which is abstract here (i.e. must be overridden in a concrete sub-class). It is also responsible for maintaining the unit of work for the active JTS transactions and allowing it to be created and looked up.

Responsibilities:

• Register a listener to the externally controlled transaction.
• Allow lookup of the unit of work for the active JTS transaction.
