I used to have this message when I instanciated a Canvas3D like this: ++ new Canvas3D(null). Now I do it like this [and it works allright]: ++ new Canvas3D(SimpleUniverse.getPreferredConfiguration());
I google yourproblem and I did found this:
....[ Try the following SOLUTION:
1) make sure that you have DirectX or OpenGL support (if not, get it from http://cochise.mta.ac.il/~dune/directx.html )
2) Go to Control panel>Display Settings> Switch to 16bit colours
hope it helps ] .....

Sujet : [JAVA3D] null graphics config? huh?
Ok, SO I have Sun's XVR-1000 (GFB) video card. I have two of them
actually.
Then I have this code:
GraphicsConfigTemplate3D template = new
GraphicsConfigTemplate3D();
GraphicsConfiguration bestGC =
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getBestConfiguration(
template );
Canvas3D sceneCanvas = new Canvas3D( bestGC );
If I run this on the first video card, it works fine.
For some reason if I run this on the second card, I get:
[EMAIL PROTECTED] 26>java KJMsoft.JLStudio.Test.DatFileTest 3001.dat
In Main()
Initializing Java3D
************************************************************************
*** ERROR: Canvas3D constructed with a null GraphicsConfiguration
*** This will cause a NullPointerException in a subsequent release

What's going wrong? Obviously 'bestGC is being set to null, but why?
