Examples of com.arjuna.mw.wst.UserTransaction

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.
