Thank you very much!

The viewport gets set in reshape and reshape gets called when the window opens.

The code works fine when I use GLCanvas and a Jframe as I told you before but I tested it with GLJPanel and JFrame and I get the same problem. When I use GLJPanel the object shows for a millisecond and than disappears completely. It has to do something with gljpanel I asume.
