An object that provides support for distributed transactions. An XAConnection object may be enlisted in a distributed transaction by means of an XAResource object. A transaction manager, usually part of a middle tier server, manages an XAConnection object through the XAResource object. 

An application programmer does not use this interface directly; rather, it is
used by a transaction manager working in the middle tier server.
