Disable the automatic closing of the JFrame using

    frame.setDefaultCloseOperation( JFrame.DO_NOTHING_ON_CLOSE );

Then add a WindowListener to the JFrame:

    frame.addWindowListener( new WindowAdapter() {
        public void windowClosing( WindowEvent event ) {
            // Decide whether to dispose the frame, exit, etc.
        }
    };
