Class XAResourceImpl

java.lang.Object
  org.ow2.jonas.ee.jdbc.XAResourceImpl

All Implemented Interfaces:

XAResource

public class XAResourceImpl
extends Object
implements XAResource

This is an implementation of XAResource used for transaction mgmt with a JDBC driver. The standard JDBC drivers don't support real XA, so the prepare will just return OK and work will be done in the commit/rollback.
