The web server actually listens for the http requests on a specific port
and if it finds that the request is made by a client for a servlet, the
web server will forward the request to the servlet engine ( which is
running on some port). The servlet engine executes the requested servlet
and sends the results back to
the client ( via the web server) .
The web server and servlet engine are both required to run servlets.
They are just two server processes running on different ports. But the
clients can only directly send their request to the web server and not
to servlet engine.
hope that is clear.
