Accessing an Image from a signed.jar

Question

Is there a quick way to grab the contents of an image file from a signed.jar? I have a Java file that creates a TrayIcon in the SystemTray which requires an image. My Java class works fine when tested, but breaks when I use it in my software and it seems that my URL object is the problem. Previously I was using TrayIconD.class.getResource(path); but it doesn't look like that works with my signed.jar file as they have different file names. Is there a way I can still use the above method or use a URL object with getContent() instead? Nether of these methods work for me

import java.awt.TrayIcon;
import java.awt.Image;
import java.awt.SystemTray;
import java.awt.AWTException;
import javax.swing.ImageIcon;
import java.net.URL;

public class TrayIconD {
    public static void main(String[] args) {
        createAndShowGUI();
    }

    private static void createAndShowGUI() {

        if (!SystemTray.isSupported()) {
            System.out.println("SystemTray is not supported");
            return;
        }

        final SystemTray tray = SystemTray.getSystemTray();
        final TrayIcon trayIcon = new TrayIcon(createImage("images/bulb.gif", "tray icon"));

        try {
          tray.add(trayIcon);
        } catch (AWTException e) {
            System.out.println("TrayIcon could not be added.");
            return;
        }
            trayIcon.displayMessage("Sun TrayIcon Demo", "This is an info message", TrayIcon.MessageType.INFO);  
        }

    protected static Image createImage(String path, String description) {
       //URL imageURL = TrayIconD.class.getResource(path);

       URL imageURL = null;
       Object image = null;

        try{ 
        imageURL = new URL("/C:/Users/Documents/notifications/images/bulb.gif");

       // System.out.println(imageURL);
       // image = imageURL.getContent();
         }
         catch(Exception ep){
         System.out.println(ep.getMessage());
         }

        if (imageURL == null) {
            System.err.println("1111Resource not found: " + path);
            return null;
        } else {
            return (new ImageIcon(imageURL, description)).getImage();
        }
    }
}
