The JCA architecture provides a standard mechanism for managing connections.
It uses a callback mechanism to notify the connection user of changes in its
state:
public interface javax.resource.spi.ConnectionEventListener {
public void connectionClosed(ConnectionEvent event);
public void connectionErrorOccurred(ConnectionEvent event);
// Local Transaction Management related events
public void localTransactionStarted(ConnectionEvent event);
public void localTransactionCommitted(ConnectionEvent event);
public void localTransactionRolledback(ConnectionEvent event);
}
