Why won't this Applet work? Any help?

Question

I followed a tutorial, though the tutorial left me to do a lot of the work. Which is good.
Anyway, I finished the Applet, but I get a message in the bottom corner of the window saying "Applet not initialized."
I can't figure out what's wrong.
I downloaded the tutorial's source code and checked it, and I think I have everything they do... I tried running the downloaded source code and it worked fine.
Here's the main class file of my Applet:
import java.applet.*;
import java.awt.*;
import java.net.*;
public class Main2 extends Applet implements Runnable
          AudioClip ballLost = getAudioClip(getCodeBase(), "beep_1.au");
          AudioClip bounce = getAudioClip(getCodeBase(), "beep_2.au");
          Player player = new Player();
          Ball ball1 = new Ball(20, this.getSize().width+40, this.getSize().height-30,1,3,8,ballLost,bounce,player,Color.red);
          Ball ball2 = new Ball(20, this.getSize().width+40, 30,1,5,10,ballLost,bounce,player,Color.blue);
          Thread th;
          Cursor c;
          Image dbImage;
          Graphics dbg;
     boolean isStopped = true;
     public void init()
          c = new Cursor(Cursor.CROSSHAIR_CURSOR);
          this.setCursor(c);
          ballLost = getAudioClip(getCodeBase(), "beep_1.au");
          bounce = getAudioClip(getCodeBase(), "beep_2.au");
          player = new Player();
          ball1 = new Ball(20, this.getSize().width+40, this.getSize().height-30,1,3,8,ballLost,bounce,player,Color.red);
          ball2 = new Ball(20, this.getSize().width+40, 30,1,5,10,ballLost,bounce,player,Color.blue);
     public void start()
          th = new Thread(this);
          th.start();
     public void stop()
          th.stop();
     public void run()
          Thread.currentThread().setPriority(Thread.MIN_PRIORITY);
          while (true)
               if (player.getLives()>0 && !isStopped)
                    ball1.move();
                    ball2.move();
               repaint();
               try
                    Thread.sleep (30);
               catch (InterruptedException ex)
                    // do nothing
               Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
     public void paint(Graphics g)
          if (player.getLives()>0)
               ball1.drawBall(g);
               ball2.drawBall(g);
               if (isStopped)
                    g.setColor(Color.green);
                    g.drawString("Double click to start.", 40, 200);
          else if (player.getLives() <= 0)
               g.setColor(Color.green);
               g.drawString("Game Over!", 40, 200);
               g.drawString("Double click to player again", 40, 300);
               isStopped = true;
     public boolean mouseDown(Event e, int x, int y)
          if (!isStopped)
               if (ball1.userHit(x,y))
                    //Need audio
                    ball1.ballWasHit();
               else if (ball2.userHit(x,y))
                    //Need audio
                    ball2.ballWasHit();
               else
                    //Play normal shot audio
          else if (isStopped && e.clickCount == 2)
               isStopped = false;
               init();
          return true;
     public void update (Graphics g)
          if (dbImage == null)
               dbImage = createImage (this.getSize().width, this.getSize().height);
               dbg = dbImage.getGraphics ();
          dbg.setColor (getBackground ());
          dbg.fillRect (0, 0, this.getSize().width, this.getSize().height);
          dbg.setColor (getForeground());
          paint (dbg);
          g.drawImage (dbImage, 0, 0, this);
}My HTML code uses <APPLET CODE="Main2.class" WIDTH=700 HEIGHT=400>.
And they are both located in the same folder.
Any idea what's going wrong here?
Thanks for any help.

Answer 1

All of the files are in the folder.
My folder contains:
Main2.class
Ball.class
Player.class
ShooterGame.html
beep_1.au
beep_2.au
And corresponding source code files.
Looks correct, right?
