    Assuming you have access to your JFrame via a frame variable, you can simply call:

    frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));

    It is probably better than calling a System.exit() as it will enable you to run some cleanup code if you have registered a window closing listener to your frame.
