How to replace the icon in the title bar and minimized window

Question

I am not sure if this is a Swing question. But since nobody answered it in the Java Programming forum, let me place it here:
I would like to set my own icon in the title bar and in the minimized window of my java application, replacing the java coffee cup icon.
I am using:
frame.setIconImage(new ImageIcon("image.gif").getImage())
as was suggested previously in the Java Programming forum at:
http://forum.java.sun.com/thread.jspa?forumID=31&threadID=5212059
This does create the icon in both places. However, it only works when I run the program from JBuilder 2006. It doesn't work if I run the program from the .jar or the .exe file.
How can I make it work for my .jar and .exe file?
Please help! Thanks!

It doesn't work if I run the program from the .jar...working example for a .jar
import javax.swing.*;
import java.awt.*;
class Testing
  public void buildGUI()
    JFrame f = new JFrame();
    Image img;
    try
      java.net.URL url = new java.net.URL(getClass().getResource("Save.gif"), "Save.gif");//correct capitalization required
      if (url != null)
        img = javax.imageio.ImageIO.read(url);
        f.setIconImage(img);
    catch(Exception e){}//do nothing - default will display
    f.setSize(200,200);
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
  public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
}
