Have you done the work-around for the Java Plug-In bug described in the
READE:

  NOTE: There is a bug in Java Plug-In that prevents standard extension
  classes, such as Java 3D, from being loaded.  Java Plug-In currently
  looks only in the lib directory of C:\Program Files\JavaSoft\Jre\1.2
  and fails to look in the lib\ext directory.  The solution is to copy
  the following four Java 3D jar files from
  C:\Program Files\JavaSoft\Jre\1.2\lib\ext to
  C:\Program Files\JavaSoft\Jre\1.2\lib:

        j3daudio.jar
        j3dcore.jar
        j3dutils.jar
        vecmath.jar

Hopefully this will fix things for you.
