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?

enter image description here

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).

Does it work? If not, do you get an error? What is the expected result, what is the acutal result? — , Jun 12 '14 at 08:05
If you want to create a file in a directory, use the proper `Path`. — , Jun 12 '14 at 08:12
I understand, but HOW i must catch it. I read images from archive using this Player.class.getClassLoader().getResourceAsStream("player.png"); — Aero, Jun 12 '14 at 08:14
Since Java 7 you can use a [Zip File System Provider](http://docs.oracle.com/javase/7/docs/technotes/guides/io/fsp/zipfilesystemprovider.html) to write to the JAR — John, Jun 12 '14 at 08:23

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.

here's link to api

good luck!
