This book will probably suit people that is fairly new to Java and wants to get to grip with Spring ASAP. Each chapter is structured in the format: "how we usually do it without spring", "why don't we try", "how do we do that", "insert example", "what just happened", then repeat the cycle to "how we do that" which couldn't in my opinion be simpler.

There are errors in examples in the book, there's no excuses as the amount of error exists in nearly every example which is insane for a book published by O'Reilly of all people. However in fairness they did release a PDF pointing out all the errors in the book and correction and most importantly they do have the example files for download so you shouldn't need to type everything out in the first place. The examples for download contains all the corrections.
Both of which is available here at O'Reilly site under "Examples", it also contains a .jar folder for most of the .jar you'll need.

Writing this in 2008, the versions of framework that it talks about is a little out of date though, so when you download the frameworks you need to make adjustments to the .jar filenames in all the ant script it provides (its not hard, just something you need to do to get every example running).

Sorry for long post, just wanted to write a fair review after reading a few negative ones mostly dwelling on the example errors. This is a well written, down to earth book that aims to get you to grip with Spring concepts in no time, providing you already know the pains of Java without Spring.
