Tomcat docs could definitely be better (no question) ... but the nature of
servlets have changed a ***lot*** in the four or five years since Apache
JServ was first designed. And all the Tomcat docs pretty much assume you
are current with all the new concepts like web applications.
The good news is that you only have to learn this stuff once, and it works
on all modern servlet containers.
If you're just starting out on this learning path, I'd suggest the
following:
* Get the Servlet 2.2 (or, better, 2.3 -- it's going final in a few days)
specification from <http://java.sun.com/products/servlet/download.html>
and read it -- this is the standard to which all servlet containers
must conform.
* Get one of the current-generation servlet (and JSP) books to learn
about all the recent features. Look for something that covers
Servlet 2.2 and JSP 1.1.
* For learning and app development, forget the whole idea of running
Tomcat behind Apache (which is quite complex to configure). Simply
run Tomcat by itself - it can serve static content quite nicely,
whereas Apache JServ required you to connect with Apache.
* If you've used things like getServlet() in your old servlets, plan
on a major redesign instead of just a port -- there's no easy way
to emulate that in a Servlet 2.2 environment.

The only way the docs get improved is for people to submit specific
changes or enhancements ... :-)
