Write a file into Java archive (JAR)

Question

I would like to write a file into Java archive (JAR). What do I need to modify in my code?

private void menu_savegame(ActionEvent e) {
    File config = new File("config");
    try {
        FileWriter fw = new FileWriter(config);
        fw.append(Integer.toString(level.current));
        fw.append("\n");
        if (win){
            fw.append(Integer.toString(ballCount));
        }
        else{
            fw.append(Integer.toString(G));
        }
        fw.append("\n");
        fw.append(Integer.toString(liveLeft));
        fw.flush();
    } catch (IOException e1) {
        e1.printStackTrace();
    }

}

I just would like this file to be written not to the folder, but into the Game.jar file - I have there all the game resources (images).

Dont forget that JAR is a typical ZIP file. In provided link you can see how it is performed.

zip manipulation with java

eventually, use external libraries like JBoss ShrinkWrap.
