Query: A complete coverage, but very complex and bad organized book

In fact this book is a complete coverage of the java security.It is true, that the subject is quite complex and needs concentrationto be understood perfectly. However I believe this books lacks suitable examples.In my personal point of view, providing sufficient clear examples in a book,will help the reader to understand better the subject.I didn't find this important quality in this book.If somebody wants to buy a book about Java security, thismeans that he/she didn't understand completely the whole subject, justby reading the API on Sun web site and therefore he/she is looking fora better source of information that illustrates the subject in a moreconvenient and clear way. Unfortunately this book, although completein the coverage of the topics, is too far a way to be considered as a clearand easy understanding book, particularly, for those who are not alreadyseniors in Java security.
