1. This book is very useful if you read it together with the companion wookbooks. The book I read was for weblogic, which, unfortunately, was kind of out dated. It took a while to get the first example up and running. After that, the rest is quite smooth.

2. The later part of the book, starting from chapter 12, seems to be done more in a rush. Even the writing style was kind of different from earlier chapters. Also there were quite some repetitions that probably could be omitted and replaced with more elaboration and examples of the topics.
