Displays on mac but not on PC

Question

I'm making my on geometry with a TriangeleStripArray. It displays on a mac (osX.3.9) but not on any of the PC's I have tried it on. I get the canvas but not 3dObjects.
when I try to use the left mousedown to rotate (the image that isn't there on a PC) I get amessage saying:
"wgl CreateContext failed, pixel format is invalid"
I don't know if this is related.
The code looks like this:

Answer 1

Found the answer to this one myself.
Load the most recent version 1.3.2 of java 3D and everything is sweet.
The version available on Sun (1.3.1) has problems with some recent device drivers
