Query: Outdated, incorrect information. Stay away!

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.
