The web container is responsible. The mapping of request URLs to JSPs,
Servlets or static content is defined by the web application's
deployment descriptor. These "rules" are used by the web container to
determine how to dispatch the incoming request. This is all defined in
detail in the Servlet specification, chapter SRV.11. Grab it at

This isn't the case. The mapping rules in the deployment descriptor
must be consulted to determine where the request is dispatched to.

The web container deployment descriptor (see above).

I'm not sure about IIS but when integrating Apache with Tomcat, you need
to configure Apache to forward all requests under certain URL contexts
to be handled by the (external) Tomcat web container. When the request
is received by Apache it forwards it to Tomcat which then applies the
URL mapping rules and determines which Servlet/JSP to invoke.
