Freemind is a mindmapping application that allows you to output your mindmap as a java "application". Using an html file, a .jar file, and a .mm file (the mindmap file) you are able to display mindmaps in the browser. Using Apache web server, I was easily able to (with a default install) view the mindmap in the browser without any problems.
However, when I switched over to IIS7.0, I was unable to bring the mindmap up. The browser would always pop up with an error saying "Could not open URL <URL pointing to the .mm file>" I am by no means an expert when it comes to IIS 7.0, so I was hoping someone could help me out. I am running IIS 7.0 on Windows Server 2008.
