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();
    }
}

I'm trying to play an audio clip by using Applet's newAudioClip()
method. That method takes a URL. The .wav file is located in a jar file
(the only jar file). For example:
if myJar.jar is the only jar file
"java -jar myJar.jar" launches the application correctly and everything
is wonderful. My audio clip won't play because I don't know how to
access the .wav file from the jar file.

This code snippet works fine when I'm not running from the jar file:

        try
        {
            File currentDir = new File(".");
            URL currentDirURL = currentDir.toURL();
            URL url = new URL(currentDirURL, fileName);
            AudioClip clip = Applet.newAudioClip(url);
            clip.play();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

It knows to look for the sound file in the current directory. How do I
adjust this code to look for the sound file in the jar.

I have a feeling it's an easy answer involving class.getResource().....

You answered it yourself - URL Class.getResource(String name)
