   public static void main (String[] args) {

       String mapFile = "/usr/people/simoes/Training/teste/data/OUTLSUPW";

       JFrame frame = new JFrame("Travel Routes");
       frame.addWindowListener(new WindowAdapter()

           public void windowClosing(WindowEvent e)
           {
               System.exit(0);

       }
       );

       TravelRoute Routes = new TravelRoute(mapFile);
       frame.getContentPane().add(Routes.display.getComponent());
       frame.setSize(500, 500);
       frame.setVisible(true);
   }
}

Ps. Ane tips for a newbie? :)

Thanks in advance,
