Hello everybody. I can't run example from sample tutorial at "http://jogamp.org/wiki/index.php/Using_JOGL_in_AWT_SWT_and_Swing". It is in the section about "jogl in swing"...
I got an exception... Here is the stack trace:
-----------------------------------------

additional information:
- I am using jogl2.0-b510 build.
- Platform: Linux ubuntu 11.10 amd64
- java: java-7-openjdk-amd64

i have already solved this problem...
i don't really understand all dependencies, but the decision was to install proprietary jdk6u27 from Oracle...
