Class JTATransactionImpl

java.lang.Object
  org.jpox.TransactionImpl
      org.jpox.JTATransactionImpl

All Implemented Interfaces:

javax.transaction.Synchronization, Transaction

public class JTATransactionImpl
extends TransactionImpl
implements javax.transaction.Synchronization

A transaction that is synchronized with a Java Transaction Service (JTA) transaction. Works only in a J2EE environments where a TranactionManager is present

When this feature is turned on, transactions must be controlled using javax.transaction.UserTransaction, not e.g. using PM.currentTransaction().begin(). Should also work for SessionBeans, as per spec UserTransaction reflects SessionBean-based tx demarcation. Transaction
