install on Netware

I want to install LimeWire on my Novell Netware server, which is v5.1.SP2a with JVM 1.2.2 (beta). I can "almost" get it all to work...

WHAT HAPPENS
From the server's command-line, I run
java -cp sys:\install\limewire-other.zip install
and it loads the Netware JVM GUI and seems to install the program. But then it close without any message. I switch back to the command-line and see several messages re "Unable to load UNAME" and "Unable to load SH". I assume this is because the installation is expecting a Unix OS.

So, then I try running the files that were copied to the new SYS:LIMEWIRE folder. I run
java -verbose sys:\limewire\limewire
and it starts to load but then fails with the error, "exception in thread 'main' NoClassDefFoundError".

What does it all mean?
Is it possible that your Java is not compatible with Novell's JVM (which I thought wasn't possible)?
Do I need to manually change the environment somehow?

Thank you for any help,
Tony
