Does anyone know why this wont play? The wav file is located in the jar
file found on the classpath. What am I missing?

import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;

public class SoundPlayer
{
    public void playSiren()
    {
        URL url = this.getClass().getResource("threeHorn.wav");
        AudioClip clip = Applet.newAudioClip(url);
        clip.play();
    }

    public static void main(String[] args)
    {
        new SoundPlayer().playSiren();
    }
}

Looks like the program is ending before the AudioClip can play. Try
putting a sleep after playSiren();
