Freemind plug-in path problem

I seem to have created a small problem for myself, so I'm wondering if there's a work-around: When I installed XWiki into Tomcat, I installed it by copying the war file in as "archwiki.war" so that the URL would be http://server.name.org/archwiki instead of http://server.name.org/xwiki. Everything seems to work find, with the exception of the Freemind plug-in. When I view the page source, I noticed that it's trying to get the plug-in jar file from "/xwiki/freemind/freemind.jar". So, is there a way to change the configuration so that it looks in /archwiki instead of /xwiki? Thanks, </CR>
