Your book was awesome. I can't see any question in the exam, coming from some other book. I have given the book to all my colleagues at my office. And even they have praised the book.
I have a request for you, please add explanation for Session Beans - web service technology. Which is currently not available in your book. And please make Message Driven Beans explanation more elaborative.
Other than these, your book was mind blowing.
Thank you very much for creating this book. I don't know how many more will get BCD certified, because of your book.
