Thanks for your helpful replies, I have VisAD up and running and looked through examples provided. Great software! I've found what I was doing wrong and summarizing the correct way below, may be it will be worthwhile to put some of it into README file with installation notes for VisAD (Windows NT instructions). I am sure it will save time to idiots like me or who went from Unix to WinNT. Hardware: Compaq, EN500, 128MB RAM OS: Windows NT 4.0 SP4 Java: Platform 2 JDK1.2.2 Java 3D: 1.1.3 Compiler used: nmake which came with Visual C++ 1. Installed JDK1.2.2 in <installdir>; 2. Installed Java 3D in <installdir>; 3. Followed instructions in VisAD README file (pay attention to CLASSPATH and set it under Start/Settings/Control Panel/System/Environment); 4. compiled VisAD using nmake as described in VisAD's README; 5. added every jar file to my CLASSPATH variable from <installdir>/jre/lib/ext/ directory; 6. added <installdir>/jre/bin path to the PATH variable (also under Start/Settings/Control Panel/System/Environment), system needs to find necessary dlls; All examples worked like a charm.
