What do I need to get started with Java 3D?
I had some problems with running the Java3D applets in a browser. I had to copy the files in the jre/lib/ext to the jre/lib directory. If this doesn't work you should check the path and the classpath and if it still doesn't work I wish you a lot of courrage on finding a solution. (I spent three days on looking for it but its worth of it.)
