How to load icon from resource in Java?

Possible duplication (solved): https://stackoverflow.com/a/1133132/783469

I have icons (jpg, png) for my application, which is stored in my directory /var/tmp/gameXbox/src/image/<here>. Now, How can i use them in application, without using hard link but as resource?

Example: not working

IconForMyButton = ImageIO.read(new File(
                    ClassLoader.getSystemResourceAsStream("image/button1.png")
                  ));

Works when i do with hard link:

IconForMyButton = ImageIO.read(new File(
                      "/var/tmp/gameXbox/src/image/button1.png"
                  ));
