public class MidiApplet extends java.applet.Applet {

 public void init() {
   java.net.URL tuneURL =
     this.getClass().getResource("Take5.mid");
   play(tuneURL);
 }
}
</sscce>

Where 'Take5.mid' is in the same directory as the applet and HTML.

But ..what does this have to do with c.l.j.machine?
