A JDBC driver or a JMS provider implements this interface to support the association between a global transaction and a database or message service connection. <p>The XAResource interface can be supported by any transactional resource that is intended to be used by application programs in an environment where transactions are controlled by an external transaction manager. An example of such a resource is a database management system. An application may access data through multiple database connections. Each database connection is enlisted with the transaction manager as a transactional resource. The transaction manager obtains an XAResource for each connection participating in a global transaction. The transaction manager uses the <code>start</code> method to associate the global transaction with the resource, and it uses the <code>end</code> method to disassociate the transaction from the resource. The resource manager is responsible for associating the global transaction to all work performed on its data between the start and end method invocations. <p>At transaction commit time, the resource managers are informed by the transaction manager to prepare, commit, or rollback a transaction according to the two-phase commit protocol.</p><P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ========
