/**
 * 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>
