# Interface XAConnectionFactory

All Superinterfaces:
  `ConnectionFactory`

All Known Implementing Classes:
  `DataSourceXAConnectionFactory`, `LocalXAConnectionFactory`

public interface XAConnectionFactory extends ConnectionFactory
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 the ManagedConnection a way to enlist a connection in the transaction.

Since:
  2.0

      `createConnection` in interface `ConnectionFactory`
    Returns:
      a new `Connection`
    Throws:
      `SQLException` - if a database error occurs creating the connection

  - ### getTransactionRegistry

    TransactionRegistry getTransactionRegistry()
    Gets the TransactionRegistry for this connection factory which contains the XAResource for every connection created by this factory.
    Returns:
      the transaction registry for this connection factory
