JFrame Icon problem

Question

Hi I have manage to create a JFrame Icon & display it properly by running java <filename>.java it did show the frame & icon. But when i Put it into a JAR file, it cannot locate the Icon anymore (the icon folder are also in the jar file). How do I ask my testFrame.java file reference the icon in the jar file?

try doing it this way
import java.net.URL;
import java.awt.*;
import javax.swing.*;
import javax.imageio.ImageIO;
class Testing extends JFrame
  public Testing()
    Image img;
    try
      URL url = new URL(getClass().getResource("Save.gif"), "Save.gif");
      if (url != null)
        img = ImageIO.read(url);
        setIconImage(img);
    catch(Exception e){/*do nothing - default will display*/}
    setSize(100,100);
    setLocation(400,300);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JPanel p = new JPanel();
    getContentPane().add(p);
  public static void main(String[] args){new Testing().setVisible(true);}
}
