Creating Java Applet to Play .au File on Startup

I have been hacking for the last few days, but cannot get it to compile. I think I am missing something obvious.

Answer:
Here's an example of how to play an audio clip from an applet. The following applet plays a short audio clip whenever the user visits that Web page:

import java.applet.*;
import java.awt.*;
import java.net.*;

public class AudioPlay extends Applet {
       String loopFile = "music.au";
       AudioClip clip;

       public void init() {
             clip = getAudioClip(getCodeBase(), loopFile);
             start();
       }

       public void start() {
               clip.play();
       }

       public void stop() {
               clip.stop();
       }
}
