Well, it seemed Sun stopped maintaining JoGL, so there's the last-updated sun version of JoGL that's 1.-something. These days, a it's being done privately by
http://jogamp.org/jogl/www/ . It's relatively simple to migrate code from JoGL 1.1 to JoGL 2.0, although not very well documented, and supposedly they've done a lot to make it work better.
Here's the problem, Bert- I'd love to show you the stuff I made using JoGL 2.0, but for the life of me I can't figure out how! The problem is the native libraries, and some nonsense to do with signed and unsigned jars- I'm talking to the folks over on the Web Start forum, but it seems crazy to me how complicated it is to just get your code in a form that someone else can see the program.
