XSLT Processor and Java, help GREATLY appreciated

[angel <an...@sb...>]

Hi.  Can someone please help?
 
I've just installed XSLT-processor version 2.1 in emacs and all looks
good so far, the XSLT Menus are there, etc.
 
But when I try to Apply XSLT to an xml file, I get this in my *xslt*
buffer:
 
" Couldn't find or load essential class `java/lang/Object'
java.lang.NoClassDefFoundError java/lang/Object "
 
 
I've never used java through emacs so I think this is where I need help.
Here's the version of java on my machine:  
 
mojave% java -version
Kaffe Virtual Machine
Copyright (c) 1996-2000
Transvirtual Technologies, Inc.  All rights reserved
Engine: Just-in-time v3   Version: 1.0.6   Java Version: 1.1 
 
I have not installed JDEE - is that what I need?  Or do I have to just
set some CLASSPATH?  How would I do that?  I'm not much of a java user.
 
THANKS!!! LORI  -- Please include reply to an...@sb....
