JSP pages not working on IIS 7.5


I'm new to this so please bear with me.

I'm trying to setup a web site on IIS 7.5 running on Windows 2008R2.

I have the site working to a point. When I browse to the site from within IIS manager, I get the following error:

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

Requested URL http://localhost:80/testsite/testdirectory/testpage.jsp
Physical Path C:\inetpub\wwwroot\testsite\testdirectory\testpage.jsp

All my other pages work except the *.jsp when accessed from a Windows 7 desktop, it just return a 404 error.

I found the following link:

It references IIS 6 and Windows 2003 server and there is a dead link. Is there an updated version to this for IIS 7.5 on Windows 2008R2?

This link suggested I install Tomcat, which I have done (version 7.0.26). Here I have my site working, too a point! The *.jsp pages work as does the htlm pages. However tomcat is not displaying any of the *.gif files. I'm just about to look in to this but any suggestions will be gratefully received.

I would like the site to work in IIS, so again any suggestions will be gratefully received.

Many thanks.
