* XAConnectionFactory is an extension of ConnectionFactory used to create connections
* in a transaction managed environment. The XAConnectionFactory operates like a normal
* ConnectionFactory except a TransactionRegistry is provided from which the XAResource
* for a connection can be obtained. This allows the existing DBCP pool code to work with
* XAConnections and gives a the ManagedConnection a way to enlist a connection in the
* the transaction.
