Problem using eclipse and jogl

Hi,
i’ve just discovered Jogl a few days ago and i decided to use it with eclipse. I followed all the installation’s steps for windows users writtend in the beginner guide and then i wrote just a little test to see if the library works under eclipse.
The test was:

when i tried to run this test i received the following errors:

i can’t understand why i receive this error even if i made all the stuff to have a correct binding between eclipse and jogl library. Can someone help me?

do you have the gluegen-rt.jar on your classpath?

yes i have it.

Please double check. I can’t think of any other reason for this error. See http://www.java-gaming.org/forums/index.php?topic=15868.0 for a more detailed description how to set up jogl in eclipse. If this doesn’t help, try to outline the steps you have taken to install jogl on your system. If you have installed another jogl-version in your jre/ext folder, please make sure to remove it, since this could probably cause your problems.
