Java lwjgl applet noclassdeffound

I'm trying to use my java applet on a html document but It just keeps giving the same errors over and over again. I'm using eclipse. When i debug/run the applet it all works fine, but when I export it to a jar file and try to use it with a html document it gives this error:

java.lang.NoClassDefFoundError: org/newdawn/slick/opengl/Texture

Here is my java code: http://pastebin.com/B3R6nj1a

This is what the .jar file contains:

-lib
  -jars
    lwjgl.jar
    lwjgl_util.jar
    slick-util.jar
  -natives-win
    *all the dlls*

-META-INF
  -*files*

-res
  grass.png
  wood.png

.classpath
.project
Camera.class
Main$1.class
Main$2.class
Main.class

I do have everything right in the build path from my project. (So added the three external jars. And added native-win to lwjgl.jar)

This is my html code:

<html>
<head>
</head>
<body>
   <applet archive='3dtest.jar' Code='Main' width = "640" height = "480"></applet>
</body>
</html>

I've also tried to change "Code='Main' " to "Code='Main.class'" also didn't work.

Does anybody has any idea why I'm getting the error? Thanks in advance.

-Tim

EDIT: .classpath file: http://pastebin.com/i7y4XYaf

This is what the .jar file contains:

-lib
  -jars
    lwjgl.jar
    ...

Those Jars should not be there. They should be separate Jars on the site referenced something like this:

<html>
<head>
</head>
<body>
<applet 
  archive='3dtest.jar,lwjgl.jar,lwjgl_util.jar,slick-util.jar,all_dlls.jar..' 
  code='Main' 
  width="640" 
  height="480">
</applet>
</body>
</html>

That is presuming the HTML is in the same directory as all the Jars.

You need to make sure your applet is packaged properly when deploying it. See http://docs.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html

You need to post relevant code, not everything and hope someone will pick through it all.

java.lang.NoClassDefFoundError: org/newdawn/slick/opengl/Texture means that class is not present in your classpath.
