My .class files work...but when I jar it, the swing goes crazy!!

Question

5 dukes, if anyone can get this :) :) ....
Hi, I have an application which is working perfectly when I view it using the java viewer. But when I put the whole thing into a jar.....the layout, and the swing stuff is messed up, terribly. Like Its foxused on nothing, and you have to click on where you think the button is...to make it appear, sooo strange. Here's what I have.
I put 2 panels onto desktopPane() using a GridBagLayout layout.
on panel 1, I have a whole bunch of g2d objects,
on panel 2, I have a whole bunch of Components (JButton's, JTextField's, etc..), but panel2 isn't really the problem, since when I removed panel 1, the jar ran without problems.
So It could be panel 1, or something in the main() class which sets up the panels, here is the appropriate code...
Panel 1
static class MyComponent extends JComponent {
          JScrollBar scroll;
          //          ~~~~~~~~~~~~~~Graphics Stuff~~~~~~~~~~~~~~~
          public void paintComponent(Graphics g){
          // a whole bunch of g2d things
          // ~~~~~~~~~~~~~~Component Stuff~~~~~~~~~~~~~~~
          MyComponent() {
                    setBackground(Color.pink);
                    setBounds(0,0,500,500);
                    setBorder(BorderFactory.createLineBorder(Color.pink,10));
                    scroll = new JScrollBar(JScrollBar.VERTICAL,0,20,0,100);
                    scroll.setBounds(484,0,16,500);
                    scroll.setVisible(true);
                    add(scroll);
                    System.out.println(scroll.isEnabled() + "" + scroll.isVisible() + scroll.getBounds());
                    setVisible(true);
And the main code...
     public static void main(String[] args) {
          //This section converts to windows look
          try {
          UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
          catch (Exception ex) {
          ex.printStackTrace();
          SwingUtilities.updateComponentTreeUI(frame);
          frame.pack();
          //~~~~
          componentPanel = new JPanel(); //initialize panel to place the component with buttons and stuff
          mc = new MyComponent(); // initialize the component with the g2d stuff
          mc.setSize(500,500);
          buttonComponent = new MySwingSwing(); // initialize the buttons and stuff
          componentPanel.setBorder(BorderFactory.createLineBorder(Color.GREEN));
          componentPanel.add(buttonComponent);
          JScrollPane scrollPane = new JScrollPane(mc);
          //~~~~~~~~~~~~~~~~~~~~~~~~~~~~Layout Stuff~~~~~~~~~~~~~~
          GridBagLayout grid = new GridBagLayout();
          constraints = new GridBagConstraints();
          frame.getContentPane().setLayout(grid);
          frame.getContentPane().setLayout(grid);
          constraints.weightx = constraints.weighty = 10.0;
          constraints.fill = 1;
          grid.setConstraints(componentPanel, constraints);
          grid.setConstraints(scrollPane, constraints);
          System.out.println("constraints are " + constraints.BOTH);
          scrollPane.setBackground(Color.green);
          frame.getContentPane().setBackground(Color.RED);
          buttonComponent.setBackground(Color.BLUE);
          frame.getContentPane().add(scrollPane);
          //frame.getContentPane().add(buttonComponent);
          frame.getContentPane().setVisible(true);
          scrollPane.setVisible(true);
          buttonComponent.setVisible(true);
          frame.getContentPane().requestFocus();
I dont know what I did wrong, but If you can find it Ill give u 5 dukes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Here is how it looks when its run as a .class file,

Dude, throw GridBagLayout out! Go get TableLayout or FormLayout! Seriously. Unless you are restricted to use only JDK layouts, TableLayout has been a huge time saver and life saver for me. Google it, you'll thank me a million times over, and toss me them 5 dukes. ;)
