Ebook: Professional WebObjects with Java

The code examples in this book didn't work.
There was no consistent flow.
Too many authors and no editor or proofreader.
Years of Java experience didn't help in understanding this book, when examples don't work, it's impossible to guess is it the framework that is failing or poor writing?
For a beginner, I highly recommend Joshua Marker's book. WebObjects is little known and used, I almost gave up exploring it until I saw on a discussion board to pick up other Webobjects books.
This book is no longer in print, and it's no wonder why!!!!!
