i had a fully work project in ubuntu 9 with eclipse. Now i have installed Ubuntu 10.10, get the backup back, downloaded Eclipse and try to run the project.
The project folder was not changed at all! But now it does not work:
Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path
If i go to "project properties > java build path > libraries" gluegen-rt.jar and jogl.jar are present and i have no compilation error ("import javax.media.opengl.GLAutoDrawable;" has no error so classes are loaded correctly i think)
i tried to install JOGL from synaptic too.
Here the full error stacktrace:

i found the problem!
ECLIPSE SAVE ABSOLUTE PATH OF EXTERNAL JARS
In your eclipse project properties -> Java Build Path, go to your library, find the gluegen-rt.jar, expand it, and click on Native Library Location and enter the location for the native libraries that came with your JOGL download.
after reinstallin ubuntu i changed my home folder structures.
