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.

    if (o == null)
      return;
    try {
      PooledConnection pooledCon = (PooledConnection) o;
      pooledCon.close(); // call close() of PooledConnection
      pooledCon.removeConnectionEventListener(this);
      log.debug("StandardPoolDataSource:expire close the connection");
    } catch (java.sql.SQLException e) {
      log.error(
        "StandardPoolDataSource:expire Error java.sql.SQLException in StandardPoolDataSource:expire");
