Hi, I don't know so much about VMWARE, but from what you have described, it's a sort of win2000 emulator on top of whatever linux distribution you have. So exactly that's your problem: java3d needs a real 3D graphics device, not an emulated one (if there is any !!!).
Question: why don't you run your HelloJava3Da directly under linux ? That way you should have access to the actual OS graphic driver.

I can run "javac HelloJava3Da.java" and produce HelloJava3Da.class. If I copy this HelloJava3Da.class into my old computer in which java3d was already installed, "java HelloJava3Da" can work very well in the win2000 of old computer. But if I run "java HelloJava3Da" in this VMWARE win2000, at first windows will remind me:"No compatible device found. Please switch to other display mode and try again!". Then I pressed "OK". Then in the DOS command line, this will appear: ************************************************************************ *** ERROR: Canvas3D constructed with a null GraphicsConfiguration *** This will cause a NullPointerException in a subsequent release ************************************************************************ Exception in thread "main" java.lang.NullPointerException: Canvas3D: null Graphi csConfiguration at javax.media.j3d.Canvas3D.<init>(Canvas3D.java:1100) at javax.media.j3d.Canvas3D.<init>(Canvas3D.java:1065) at HelloJava3Da.<init>(HelloJava3Da.java:52) at HelloJava3Da.main(HelloJava3Da.java:80) I really wonder why. Because in the old computer, this class works well. I do not think there are some problems about Canvas3D, maybe just the problems of display mode. But there is only one color mode in VMWARE win2000: high Color(16 bit). No possibility to change this. What should I do to let "java HelloJava3Da" work?
