Class WASManagedRuntime

java.lang.Object
  org.apache.openjpa.ee.WASManagedRuntime

All Implemented Interfaces:

ManagedRuntime, Configurable

public class WASManagedRuntime
extends Object
implements ManagedRuntime, Configurable

ManagedRuntime implementation that allows synchronization with a WebSphere managed transaction.

WebSphere Application Server does not expose the TransactionManager to an application. Instead it provides a proprietary interface to register for synchronization and obtain transaction ids.

WASManagedRuntime provides the wrapper classes needed to interact with the WAS proprietary interface and the OpenJPA kernel.
