 
                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.
