public class ResourcePOATie

extends ResourcePOA

The Transaction Service uses a two-phase commitment protocol to complete a top-level transaction with each registered resource. The Resource interface defines the operations invoked by the transaction service on each resource. Each object supporting the Resource interface is implicitly associated with a single top-level transaction. Note that in the case of failure, the completion sequence will continue after the failure is repaired. A resource should be prepared to receive duplicate requests for the commit or rollback operation and to respond consistently.
