I made jSat, small java 3d-library, using lwjgl.
I stopped coding it last year because i switch to c# but maybe you will find
something useful in it.
You can load it http://dhost.info/haima/jsat.php
, click "jSat + esimerkit" (jsat+examples) link.
It uses older lwjgl but i think it works new lwgjl too, maybe some code changes.
Sorry, no documentation and all code comments are in finnish (like that web page).
And that md5 loader is buggy (bad port from c), so it is useless.
Obj-loader, glsl, shadows etc works quite well.
