-/** <p>The XAResource interface is a Java mapping of the industry standard
-  * XA interface based on the X/Open CAE Specification (Distributed
-  * Transaction Processing: The XA Specification).
-  *
-  * <p>The XA interface defines the contract between a Resource Manager
-  * and a Transaction Manager in a distributed transaction processing
-  * (DTP) environment. 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>
-  *
