I'm going to move this to our servlets forum

At a glance, your deployment descriptor (web.xml file) looks fine.

If you want to avoid the need to configure a servlet for each and every component you write, look up the Front Controller or Command pattern.

We have an example in our code barn under Servlets.
Also Bear Bibeault has written an article in our Journal about the front controller pattern as used by his FrontMan framework.

The article Ben mentioned.

Also, an implementation of Front Man is available. Click on link in my sig.
