I think this is a problem explained in our README:
NOTE: The Java2 SDK 1.2 installs Java into both the JDK location
(c:\jdk1.2.2 by default) and into the JRE location
(C:\Program Files\JavaSoft\Jre\1.2 by default). Additionally, a
shortcut to java.exe is installed in the WINNT/System32 (for NT
systems) or Windows/System (for Windows 95 & 98) directory.
Developers need to be aware of this when working with the Java2 1.2 SDK.
Unless the path to the 1.2 SDK bin directory is placed in the PATH
environment variable ahead of the system directory, the SDK java.exe
will not be executed. If any extensions (such as Java 3D) are only
installed into the SDK and not the JRE as well, then these extensions
will not be found during program execution.

More from the README:
If, after installation, you get the following error message while
running a Java 3D program:
java.lang.UnsatisfiedLinkError: no J3D in shared library path
It is most likely because OpenGL and/or the OpenGL GLU utilities are
not installed on the machine.
For information on OpenGL and how to get it, see the OpenGL web page at
http://www.opengl.org/
Hopefully these will solve your problems.
