Hi...

I wrote about this to the list a while ago and never could quite figure out my 
problem.  It involves the fact that my XMLUI interface's Home page won't appear.
Since we normally use JSPUI, I was able to put this on a back burner, but now 
that I am working on migrating to 1.7.1, we are also planning on moving on to 
XMLUI.

So, here's the situation:  when I go to the XMLUI version of the Home Page of 
my site, I only get a blank page.  The other pages (community-list, browse 
pages, item display) all display correctly, but the Home page doesn't.

For my testing I am using the Classic Theme and the Default news-xmlui.xml 
file.  When I go to the home page, Firebug shows me:
<html>
   <head></head>
  <body></body>
</html>

And not the news-xmlui.xml content.

If I do a http://<mysite>/DRI<http://%3cmysite%3e/DRI>, I get "XML Parsing 
Error: no element found" for my home 
(http://<mysite>/DRI/community-list<http://%3cmysite%3e/DRI/community-list> 
works, so I know that the protocol I'm using is correct)

By the way, I am using /xmlui as my Tomcat webapps ROOT (defined in my 
server.xml config file).

Any ideas out there?

In the logs, I see:
ERROR org.dspace.app.xmlui.cocoon.DSpaceCocoonServletFilter @ Serious Error 
Occurred Processing Request!
javax.servlet.ServletException: Servlet execution threw an exception

I'm stumped, and I can't see what is causing the error.  Here is the full error 
report:
