It covers a fairly broad area, and I did find parts of it useful but I was expecting more difficult problems to be addressed. Many examples I had already worked out for myself, such as login routines....

Also the three chapters of the book explains how to (1) write servlets, (3) name them and set up directives and (2) the setup of Tomcat and Web Logic. I wouldnt have expected a cook book to waste time telling you how to turn the oven on. Tomcat could have been dealt with in one page, telling you how to install it, connect to localhost and find the documentation on the start page.

If you are new to Java (with a little basic knowlege) this is a pretty good book. It doesnt waste time and does have code you will find useful.

If like me your looking to move from intermediate to advanced its a good overview, does allow you to check your understanding and consolodate your learning, but wont move you forward.
