Query: Not for Beginners

In my opinion, this may be a good reference book if you already knowJ2EE, but it is not a good book for learning J2EE.In general, this book talks about J2EE concepts, but it does not teachthem.All too often, the authors explain concepts in terms of concepts thatthey have not explained. In many cases, they don't give usefulexamples or illustrations in their explanations. Thus, in order tofollow many of their explanations, you have to already know theconcepts.After studying seven chapters in this book, I decided to look elsewhere.Because I believed that this book would be a useful tool in my effortto learn J2EE, and because it has not been very useful in that effort,I will only give it one star.
