Path to read a sound out of my package

Question

I have a Sons class which load and play sounds. And an adhd class which contain the main and uses this Sons class.

All my classes are in the package "adhd" and my sounds in the jar, are like this : 1.wav is in SoundN which is in the jar. (ADHD.jar/SoundN/1.wav).

When I run the code in Eclipse it works, but when I run the jar it doesn't. It is important for me to keep the sounds "loading" because I need my program to read my sounds quickly, as I am using timers. What do you suggest me to do?

Here is the code of my class Sons which load sounds in instances of singletons.

Sons

package adhd;

import java.io.File; 
import java.io.IOException; 
import javax.sound.sampled.AudioFormat; 
import javax.sound.sampled.AudioInputStream; 
import javax.sound.sampled.AudioSystem; 
import javax.sound.sampled.DataLine; 
import javax.sound.sampled.FloatControl; 
import javax.sound.sampled.LineUnavailableException; 
import javax.sound.sampled.SourceDataLine; 
import javax.sound.sampled.UnsupportedAudioFileException;
import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;

public class Sons {
    private static String PATH=null;
    private static Sons instance;
    private final Map<String, Clip> sons;
    private boolean desactive;

    Sons(String path) {
        PATH = path;
        sons = new HashMap<String, Clip>();
    }


    public void load(String nom) throws UnsupportedAudioFileException, IOException, LineUnavailableException {
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(getClass().getResourceAsStream(PATH + nom)));
        sons.put(nom, clip);
    }


    public void play(String son) {
        if(!desactive) try {
            Clip c = getSon(son);
            c.setFramePosition(0);
            c.start();
        } catch(Exception e) {
            System.err.println("Impossible to play the sound " + sound);
            desactive = true;
        }
    }
}

Here is the adhd class which contain the main that uses sounds

Main class : adhd

public static void main(String[] args) {

    Sons sonN= new Sons("/SoundN/");

    try {
        sonN.load("1.wav");
    } catch (UnsupportedAudioFileException | IOException
            | LineUnavailableException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    sonN.play("1.wav");
}

Now, thanks to the exception message, we know what the problem actually is. The problem is not that the sounds can't be loaded or aren't found in the jar. The problem is that, as the javadoc says:

These parsers must be able to mark the stream, read enough data to determine whether they support the stream, and, if not, reset the stream's read pointer to its original position. If the input stream does not support these operation, this method may fail with an IOException.

And the stream returned by Class.getResourceAsStream(), when the resource is loaded from a jar, doesn't support these operations. So what you could do is to read everything from the input stream into a byte array in memory, create a ByteArrayInputStream from this byte array, and pass that stream to AudioSystem.getAudioInputStream().

If loading everything in memory is not an option because the sound is really long (but then I guess you wouldn't put it in the jar), then you could write it to a temporary file, and then pass a FileInputStream to AudioSystem.getAudioInputStream().
