Help Problem deploying Maverick (friend.jsp) to Orion

Hello
 
Sorry to bother you all, but I'm just reading about Maverick (and am very
excited about it and its philosophy), but I am having trouble running the
examples on the Orion app server (v1.5.2).
I've installed and run under both Window and Unix without success, although
the output is somewhat different - see below.
 
 
 
Under Windows 2000
--------------------------------
 
The output the browser returns is: 
 
500 Internal Server Error
java.lang.RuntimeException: Error instantiating XML parser: Missing
'tagclass' in tag definition

            ....
 
and the last portion of the log4j output reads:
 
...

Under Unix
-----------------
the output the browser returns is: 
 
            Page cannot be displayed
 
and the last portion of the log4j output reads:
 
...

Any ideas would be greatly appreciated.
