How to use an applet with packages in a jar

Question

I have an applet (Applet, not JApplet) that has a lot of classes organized into packages, including the applet itself. I have looked everywhere for how to use that jar as an applet. It is not runnable and has a manifest file like such:

Manifest-Version: 1.0
Class-Path: AppletSource.jar

I put it in an html (Game.html), as such:

<applet code="Game/Game.class" archive="Game.jar" width=800 height=600>
Your browser needs JAVA!!!
</applet>

As you can see the class is called Game.class, Package Game and the jar Game.jar. The manifest is in Game.jar/META-INF

When I use the appletviewer Game.html I get an error (java.security.AccessControlException: access denied) and if I open the .html I get a ClassNotFoundException: Game.Game.class. What can I do?

Try opening it with [Appleteer](http://pscode.org/appleteer/), which does more checks and produces more detailed output. — Andrew Thompson, Feb 17 '12 at 04:22

try

<applet code="Game.Game" archive="Game.jar" width=800 height=600>
Your browser needs JAVA!!!
</applet>

Also check that the package name is really Game and not game.

I don't like using that convention so yes, that's its name is with uppercase – rdelfin Feb 16 '12 at 22:53
PS: It doesn't work with Game.Game, Game.Game.class, Game/Game or Game/Game.class – rdelfin Feb 16 '12 at 23:09

The format for the applet code attribute is from oracle doc "The value appletFile can be of the form classname.class or of the form packagename.classname.class.". This file is relative to the base URL of the applet. It cannot be absolute. Also try adding the jar in the same directory as the html.

For some further information see this doc http://docs.oracle.com/javase/1.4.2/docs/guide/misc/applet.html
