I have made a zip with everything in it.http://www.myjavaserver.com/~captainjester/lwjgld3d.zip
There are 5 test classes:
The last one just puts a triangle on the screen.
The first 4, as you may have guessed, are done from Drunken Hyena's tutorials. The World Transform one is very slow compared to the C++ version on his site, so there still needs to be some tweeking done. I am sure your experience with OpenGL will help.
I have completed the native code for IDirect3D9, IDirect3DDevice9 and IDirect3DVertexBuffer9. The rest are just stubbed out.
