How to configure IIS to redirect SERVLETS to TOMCAT 3.2

[Ved Antani]

I am using Win NT 4 with IIS (Service Pack 6a). And Tomcat 3.2.
All the JSPs work fine but as I try to use a servlet class, the 404 error starts creeping in.
I cant understand why this can happen that IIS redirects all .jsp files to Tomcat but it does not redirect .class files (in the same directory) to tomcat.
Please give me some hints...
