Tagir, VisAD does not yet support Java3D 1.2. Try switching from the beta back to Java3D 1.1.3. I'm not even sure Java3D 1.2 beta is compatible with JDK 1.2... you might need to be running the JDK 1.3 beta for it to work properly. But the safest course would be to stick with JDK 1.2 and Java3D 1.1.
