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 transaction.
Since:2.0

Create a new Connection in an implementation specific fashion.

An implementation can assume that the caller of this will wrap the connection in a proxy that protects access to the setAutoCommit, commit and rollback when enrolled in a XA transaction.

Throws:
  • SQLException – if a database error occurs creating the connection
Returns:a new Connection
