Java 3D requires Java 1.2.2 or higher from Sun Microsystems:

You don't have Java 3D installed into your SDK. The current
release of Java 3D has two installers - a JRE one and an SDK one.
You need to install both to get Java 3D installed into both the
JVMs on your machine. (You have a JVM in c:\Program Files\JavaSoft
and another in c:\jdk1.3\jre). To see if Java 3D is installed into a
JVM, check the lib\ext\ directory for the existence of the four
Java 3D jar files and the bin\ directory for the two Java 3D DLLs.
The next release of Java 3D has a smarter installer.
