com.arjuna.mw.wst.UserTransaction

This is the interface that allows transactions to be started and terminated. The messaging layer converts the Commit, Rollback and Notify messages into calls on this. Importantly, a UserTransaction does not represent a specific transaction, but rather is responsible for providing access to an implicit per-thread transaction context; it is similar to the UserTransaction in the JTA specification. Therefore, all of the UserTransaction methods implicitly act on the current thread of control. @author Mark Little (mark.little@arjuna.com) @version $Id: UserTransaction.java,v 1.8.4.1 2005/11/22 10:36:05 kconner Exp $ @since XTS 1.0.
