Hopefully, some of you may be a newbie like myself, so you might find the following useful:
Tons of OpenGL tutorials that will help get you started (I hope). Most of the early tutorials that I've checked also have Java source code available (VC++ is the language of choice for the actual tutorials), but I'd think with careful analysis and a bit of thought, you can figure out how to do the conversions yourself with the tutorials that don't currently have java source. And if you do figure it out, you might think about submitting it.
Cas: Have you checked out this site? Are the java sources good? Can you use them with LWJGL?
