java error accessing IIS website on same server where Tomcat lives

Tools: Tomcat with IIS
Problem: files within the Tomcat directory structure (xml or jsp) that call out to a url that is served from IIS on the same server where Tomcat is installed....are causing errors.
1. Tomcat is called to serve an xml file with the following doctype dec:
<!DOCTYPE narratives PUBLIC "-//mnhs/stories//DTD narratives//EN" "http://stories.mnhs.org/xxx/narrative.dtd ">
error in stdout.log: Error in SimpleTransform20: java.io.IOException: Server returned HTTP response code: 400 for URL: http://stories.mnhs.org/xxx/narrative.dtd
current workaround employed:
<!DOCTYPE narratives PUBLIC "-//mnhs/stories//DTD narratives//EN" "d:\xxxx\stories\xxx\narrative.dtd">

2. When i call Search.jsp, which issues a cgi search with:
<c:import url="http://stories.mnhs.org/cgi-search/mgg/search.cgi?zoom_query=${requestScope.zoom_query}&zoom_cat=${requestScope.zoom_cat}&zoom_per_page=200&zoom_and=${requestScope.zoom_and}&zoom_sort=0"/>

I get the following error in the Local_Host.log file:
2007-03-29 11:52:15 ApplicationDispatcher[/stories] Servlet.service() for servlet jsp threw exception
java.io.IOException: Server returned HTTP response code: 400 for URL: http://stories.mnhs.org/cgi-search/mgg/search.cgi?zoom_query=war&zoom_cat=-1&zoom_per_page=200&zoom_and=0&zoom_sort=0

Interesting Note:
When i paste the URL that is generated in the first line or two of the error above, the raw cgi search results come in, but the extra files (includes) that are called in by the search.jsp page that make up the site...don't.  so i'm just looking at a raw listing of the search results.

So it seems like Tomcat cannont access IIS resources on the very server that it lives on.  This app was built for our company, and i don't really know much about java.

And i'm not even sure if this is enough info to get any good feedback.
Thanks!
