I strongly encourage you to get a copy of "The Red Book." No OpenGL programmer should be without it. It's formal name is:
OpenGL Programming Guide: The Official Guide to Learning Opengl, Version 1.2 by Mason Woo, Jackie Neider, Tom Davis, OpenGL Architecture Review board, Paula Womack - Paperback - 800 pages 3rd edition (August 6, 1999) Addison-Wesley Pub Co; ISBN: 0201604582http://gamedev.net
hosts a free pdf copy of an older version at http://www.gamedev.net/download/redbook.pdf
In there you will find enough information to give yourself a solid foundation in OpenGL. Converting the C examples into jogl is trivial, so don't let that bother you. From there, you should be able to look at any OpenGL example and adapt it to your needs.
