ClassNotFound for AppletLoader when exporting a libGDX applet

问题

I tried following this to export my libGDX game as a Java applet. The guide was a bit confusing so I might have done something wrong here. This is what I did:

My libGDX game, in Eclipse, looks like this:

Game
Game-Android
Game-Desktop

The desktop game works fine.

As the guide says, the desktop project uses the Lwjgl backend.

Then I created a GameApplet.java in Game-Desktop/src/my.package.name containing

package my.package.name;

import com.badlogic.gdx.backends.lwjgl.LwjglApplet;

public class GameApplet extends LwjglApplet
{
    private static final long serialVersionUID = 1L;
    public GameApplet()
    {
        super(new Game(), false);
    }
}

I created a directory applet in Game containing

gdx.jar
gdx-backend-lwjgl.jar
gdx-backend-lwjgl-natives.jar
gdx-natives.jar
lwjgl_util_applet.jar

I right-clicked Game in Eclipse and exported it as a JAR with the following settings:

Resources to export:
 - Game
   -- src
   -- libs
Export generated class files and resources

The exported JAR (called Applet.jar) was placed in the applet folder.

I created the index.html file containing

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
  <head>
    <title>HelloApplet!</title>
  </head>
  <body>

  <div id="applet_container">

   <param name="lwjgl_arguments" value="-Dorg.lwjgl.input.Mouse.allowNegativeMouseCoords=true">
    <param name="separate_jvm" value="true">
    <param name="codebase_lookup" value="false">
  </applet>
  </div>


  </body>
</html>

I signed the files and uploaded them to my site. On Firefox, OSX, I get a message saying

ClassNotFoundException

org.lwjgl.util.applet.AppletLoader

What did I do wrong?
