Interesting… Thanks for helping me through this!
GluGen…
it was built using java 1.6 (if that makes a difference?).
The application runs perfectly fine in IDE(not even a warning).
I copied the Applet code you made (using your host) into my host and it’s still just giving me the class not found error. This is screwing with my head. If I posted code do you think it’d help you understand what may be going on?

Do Display Lists work in Applets?
