[JAVA3D] problem running the application into a JAR

[hterrolle]

Hi,   I try to run my application into a jar by executing  this command " javaw -jar xxx.jar" i setup the manifest correctly. But when i run it i cannot see nothing on the screen but the process seems to run. I have changed something but i forget it. I send the code in case or someone could see it.   thanks   public class j3d_in_swing extends JPanel {   public j3d_in_swing() {       setLayout(new BorderLayout());     screenSize = Toolkit.getDefaultToolkit().getScreenSize();  // what does the user have his resolution set too?       theOuterframe = this; // make this a global variable       image = new j3d_in_swing_Image();       menu = new MenuMgr(); // make the menus     toolbar = new TreeTableToolBar(theOuterframe);// make the tollbar     split = new SplitFrame();     }     public static void main(String[] args) {       frame = new JFrame();     new j3d_in_swing(); // make the window     frame.getContentPane().setLayout(new BorderLayout());     int WIDTH = 730;int HEIGHT = 570;     frame.setSize(WIDTH, HEIGHT);     Dimension d = Toolkit.getDefaultToolkit().getScreenSize();     frame.setLocation(d.width/2 - WIDTH/2, d.height/2 - HEIGHT/2);      // we need to manually catch the kill window event so all our threads get completely shut down     WindowListener l = new WindowAdapter() {             public void windowClosing(WindowEvent e) {                 System.exit(0); // kill all threads including the render and swing             }     };       frame.addWindowListener(l);     theOuterframe.add(toolbar, BorderLayout.NORTH);//treetable     theOuterframe.add(split, BorderLayout.CENTER);     frame.setJMenuBar(menu);  // make this the menu     frame.getContentPane().add(theOuterframe, BorderLayout.CENTER);       //frame.setVisible(true);     frame.show();   }  }
