Query: Not for software developers/engineers!

This book may be useful for marketing people, but it is not for software developers!Moreover the authors' attempt to make the book 'fun' is mediocre at best!If you are a software developer/programmer looking to develop J2EE applications, you are better off reading other books, likeHead First Servlets and JSP: Passing the Sun Certified Web Component Developer Examfor servlets & JSP andHead First EJB (Brain-Friendly Study Guides; Enterprise JavaBeans)for EJBs. Later you may want to graduate to Spring framework with a book likeSpring in Action.
