Decent, but not as good as it could have been
2010/8/4
形式:ペーパーバック|Amazonが確認した購入
I really have mixed feelings about this book: the author is definitely well versed on the subject, but his english and presentation style leave much to be desired. A little more attention ( and editing ) would have done much to make this book more readable and easier to go through. The author also shares the typical defect of researchers and scientist: not being able to discern the hard from the easy and the important from the futile, presenting all material with the same level of detail and a general dullness in the presentation style. This book does have some strong point though: it touches all aspects of JPA programming in decent detail, does not shy away from what other book consider "advanced material beyond the scope of this book" and tried to do that in a pragmatic way. Example code need a lot of work anyhow, it's given basically as a bunch of poorly organized java source files and will require quite some sweat to be put to work. Nothing that can't be done, but if I spend money on a book I expect the source code to be better organized and ready to run, at a minimum with an ant script, if it's a book on java technology. The part of concurrency and locking if far from clear and detailed enough, but unfortunately that is an evil common to all JPA books I have seen. To sum it up, this is a decent book if you have the patience to go through the example code and organize it with ant scripts or and ide to make it run on you application server of choice, but it won't be a good choice for a real beginner in JPA and J2EE technology, and a generally dull and boring read for everyone.
I do have the disturbing feeling that many of the 5 star reviewers of this text are actually friends/colleagues of the author...
This is far from a 5 star book , it's a decent text which could have been great with a little more effort and attention to the example code and presentation style...
If you have time, budget or space only for a single book on JPA I think that the best one is still
Pro JPA 2: Mastering the Java™ Persistence API (Expert's Voice in Java Technology)
though even this one is far, very far from perfect..

Quick and easy reference

I was finishing up a project using Hibernate and heading into a project using JPA 2. I snagged this book in order to prepare for the new assignment. After my first read through I have since referenced it many times and actually told a remote co-worker that he would have to buy his own because I wasn't sure I could let him borrow it for 2 weeks since I refer to it so often. Usually, I find it more difficult to use a book instead of the web, but in this case I often go to the book first.
With this book it's easy to find the information you are looking for, and there doesn't seem to be a lot of cruft. I haven't spent a lot of time in other JPA 2 books, so I can't tell you how this compares, but that said, I haven't felt like I _needed_ another book in order to do what I needed for my project.

Garbage negative reviews
2010/11/12
形式:ペーパーバック|Amazonが確認した購入
Short Summary: Best book on JPA 2.0 on the market right now (Nov 2010). I know, I've looked through almost all of them!
Long Summary:
I got this book because of the overwhelming positive reviews of the book. Although one of the negative reviews concerned me so much that I decided to rate this product.
1) The presentation is well organized! The author in Chapter 1 gives you a working sample application. If you take the time to work on the sample applications, the rest of the chapters all do into details of all the potential features of the first application. The cool thing about this approach is you already kinda understand the material from chapter one (you compiled the code, right!?), but spend the rest of the chapters understanding the details the technology examples presented in the sample app in chapter one. Although I know nothing of Daoqi Yang, I can tell he is a prof who has had experience teaching.
2) The author's written English in this book is excellent. I don't understand why someone wrote his english needed work. Frankly, I find that offensive (I'm not chinese or anything)- even though I don't even know Daoqi Yang(author). Perhaps a student of his who wrote that comment was referring to his spoken english...
3) Eclipse examples! I'm so sick of people using Netbeans tools or JDeveloper IDE when the rest of the real world uses Eclipse
4) Excellent mapping of new concepts by providing complete compilable sources! Uggggh... I hate authors who don't do that.
5) Examples of BOTH stand alone applications and EJBs. Really cool given that there are different approaches needed for both types. For some reason, most the tutorials on this topic always maps to EJBs.
I've been reading a lot of Manning books prior to this(on other topics). Although they are good too, I like the approach taken by this author (see point #1). Although, I must confess, the print itself on the Manning pages is better formatted. I love how Manning books map discussions of code by using cool graphical annotations which map back to the discussion.
