I'm not familiar with this Java 3D SDK release and what version
of Java it expects to run on. But, the java.security.PrivilegedAction
interface is new to Java 2 (wasn't in JDK 1.1.x). You may need to run
Java 3D on Java 2 Standard Edition which you can download from the
http://java.sun.com website.
