Hey vaironl, welcome to the LWJGL forum!
An excellent tutorial that I would recommend starting out with is
the Arcsynthesis tutorial. It covers 3D development with OpenGL in C++. The C++ code has been
ported to Java+LWJGL.
While going along, I highly recommend becoming familiar with the GL functions. The best way is to simply google the function name, and preferably choose the ones from 'opengl.org', not from 'khronos.org'.
In addition
the OpenGL Wiki has even more excellent documentation on all areas of OpenGL for more perusing!
Good luck!
