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
