Problem transforming XML with server XSLT in Firefox

Here are two URLs

http://library11.berkeley.edu/~gmills/binds_result.xml

http://library11.berkeley.edu:8080/noidbind/binds_result.xml

In Firefox 2, the first URL results in the XSL stylesheet referenced
in the XML document being applied correctly. The second URL does not.
The difference is that the first URL is being served by Apache httpd
1.3.X, and the second by Tomcat 6.0.

This document was generated dynamically by the app at noidbind. When I
generate the document, I set the mimetype of the document to 'text/
xml' and that also fails to work.

All of these work in IE.

Can anyone tell me what I have to do to fix this, and get the
stylesheet applied when the document is served by Tomcat?

Thanks;
