Summary: Too little too late
Review: Six months ago, as no Cocoon book existed yet, this thin volume could have been interesting, but with the release of Moczar and Aston it is simply not worth the money anymore. It is often rather superficial and is packed with questionnable fillers à la Wrox: one really wonders why the authors and the publisher felt compelled to include useless 'introductions' to css, xhtml and xsl (and more) in a book on cocoon!

Summary: Desperately seeking editing
Review: What the authors of this book desperately needed was an editor. This book is a mess. There is no sense of flow. There is no attempt by the authors to explain a topic and then delve further into it building upon what they show us. Instead we get detail. We are told Cocoon is made up of these frameworks and these frameworks use these design patterns and are made up of these pieces which are made up of these pieces. And in the end we know no more than when we started. We are told Cocoon contains these Java classes and are given a sentence explaining each one. We are given lists of SAX classes with no clear explanation of why we should be interested. There are lots of tables and lists and charts that explain nothing. The book never gives a clear explanation of what Cocoon does or how Java fits into Cocoon. The chapter on LogicSheets is a perfect example. There are thirty three tables in this chapter going page after page with no clear explanation of what the tables mean. Then the example at the end of the chapter is so trivial as to be meaningless. In fact, the examples throughout the book are much too simplistic and don't demonstrate the power of Cocoon. There is no question that an enormous amount of research went into this book. It's a shame that the authors weren't able to present that research in a useful way.

Summary: Dissapointing
Review: When I originally saw this book, I was intrigued by an alternative way of presenting this fairly complicated material and the seemingly relevant examples. I felt that it was generally incomplete and scattered. Take the section on custom Generators, for example. The example is derived from an example is a previous book written by another Sybex book on XML and JSP, so it seemed like a nice comparison with an alternative technology. The introduction to the example discusses the dynamics of a branching survey and why a custom Generator is sometimes necessary. Unfortunately, the example doesn't follow through on the promise or the lesson. The example code that I downloaded from the website turned out to be incomplete and inconsistent with the book. Although I eventually got the example running, the end result wasn't compelling enough for me to understand the purpose for writing the custom Generator in the first place. I was dissapointed and frustrated with this book. For those trying to learn about Cocoon I would suggest Zeigeler and Langham's New Riders book (Cocoon: Building XML Applications).
