Examples of javax.sql.PooledConnection.removeConnectionEventListener()

javax.sql.PooledConnection.removeConnectionEventListener()
Deregister the supplied ConnectionEventListener from this PooledConnection. Once deregistered, the ConnectionEventListener will not longer receive events ocurring in the PooledConnection. @param theListener an object which implements the ConnectionEventListener interface. This object should have previously been registered with the PooledConnection using the addConnectionEventListener method.
