jackrabbit repository utility

[Brendan Jacobs]

I am working with a web app that is having trouble looking up specific PDF
and Powerpoint files.  Is there a Jackrabbit utility that I can use to
lookup files in my repository independent of my application?  The files in
the repository are stored using a content reference so I was just wondering
if we can lookup the file either via derby or another utility.  Thanks in
advance.
