Summary: shows how to implement a framework for a web app
Review: If you program Java servlets and JSPs, chances are good that you are using Tomcat. It provides a very well debugged container for your applications. Here, Moczar walks you through version 5, the very latest.

He takes a lot of the mystery about what J2EE is, if you decide to use Tomcat to hold J2EE applications. He illustrates with a very common 3 tier architecture - client, middle and back tiers. Most crucially, with the middle tier being subdivided into a presentation layer, controller, business logic and a lowest layer that talks to the back tier. A lot of the book essentially fleshes out how Tomcat acts as a container to hold that middle tier. Plus, within that tier, how JSPs and servlets can be used to make each layer. Of course, there are many details. But if you keep the overall framework clear in your mind, then you should have no problem following his narrative.

The last part of the book is more suited for Tomcat sysadmins. Programmers usually will not need much material from this section.
