Query: This book will teach you how to be a bad JSP programmer

Total waste of money and time. This book is like a syntax reference. It fools you to believe that you are learning JSP. I DID NOT READ IT UNTIL THE END, BUT I THINK IT DOES NOT MENTION THE MVC PARADIGM. I don't have time to write all the reasons why this book is not worth your money. So just believe me: There are better books about JSP/Servlet.
