Hi
You should have looked at that:
http://jogamp.org/wiki/index.php/Setting_up_a_JogAmp_project_in_your_favorite_IDE#Eclipse_IDE_user_libraryI've just downloaded jogamp-all-platforms.7z here:
http://jogamp.org/deployment/jogamp-current/archive/jogamp-all-platforms.7zgluegen-rt-natives-windows-i586.jar isn't missing, it is in the directory "jar/" and it works perfectly when following the instructions I've mentioned at the beginning of my comment.
There is no need of adding gluegen.jar into the classpath, gluegen-rt.jar is enough. If you don't want to waste any time in uselessly tinkering our libraries, I advise you to follow our instructions.
Best regards.
Edit.: If you hadn't put gluegen.jar into your classpath, you would have had less troubles... There is no name error in our archives.
