Java and XML Data Binding

Summary: Beware of booby-traps
Review: The book contains a lot of good information on data binding. It also explains the "data binding" concept by breaking it down into "Marshalling", "UnMarshalling" and "Binding". The author has taken JAXB as a starting point to explain the "Data-Binding" framework. He has also taken the pain of going through other open source frameworks available for data-binding though they are not dealt with in great detail.
However I am a little disappointed because the author has taken a biased look at data-binding. He has not mentioned the drawbacks of data-binding in a single place. Obviously there are many drawbacks of such a approach. One of them is that your once independent data-containers are now tied to a framework. Secondly if there is a small modification made to the xml, the classes have to be re-generated and you end up with two code bases. Such issues are not mentioned in the book.

The least I would expect in such a detailed book when different frameworks are compared side by side is a comparison chart that I can refer quickly.

I give a four star rating because it contains a lot of detailed information about the data-binding framework but failed to tell why data-binding might not be the right solution.

Summary: JAXB section is out of date
Review: The book describes the JAXB api based on an early access version. The definitive version is completely different form the early access version, making this book almost useless.

Summary: Outdated, incorrect information. Stay away!
Review: This book was written before the version 1.0 release of the JAXB data binding API's. As a result much of the information in this book is incorrect and not current. If you follow the instruction in this book you will NOT sucessfully perform XML binding to java objects. For example, the book uses DTD's as the XML description model used by JAXB. This is wrong DTD's were dropped in favor of XML schemas. The instructions for using the JAXB jar files are wrong. The required jars have changed since this book was printed. The instructions for using the generated java data binding classes is wrong, the usage has changed since this book was written. The author tried to get to far ahead of the technology curve on JAXB and as a result authored this book too early in the JAXB life cycle. The book is of minimal value.

Summary: Waste of money
Review: This does not talk about JAXB at all. What it talks is about some non standardised APIs that existed before JAXB.
The brief mention of JAXB ( 4 pages ) is only philosphical. Even that is w.r.t. an obselete version with DTD support.
( Current JAXB only supports XML schema )
