Rating:  - Buy this only if you already know Java EE
This book makes sense only if you already know Java EE, but in that case you don't need it. One of the worst tutorial I've ever seen. Wasted a lot of time trying to understand what it says, but that's so hard because it keeps referring to concepts that are be not covered until later chapters (forward referencing). The examples are working, but no clear explanation on what each of them does, how to reassemble them, etc. No step by step guide. Even concepts aren't explained well enough.
Rating:  - Good Book
A Good Book. Good for getting basic examples. Doesnt go very deep on each subject.
Rating:  - very good
It's an excelent service and very fast, i have not problem with all this items
Rating:  - This is a great introduction to JEE5 as long as you already know JEE!
The book description says "This book takes a task-oriented, example-driven approach to show you how to build applications for the Java EE 5 platform."
That is a very misleading half truth. You would expect step by step instructions to write and deploy simple examples. Well the authors have decided to take a short cut instead. They say 'Here is a nice little example we have written the other day. And we will just tell you how to deploy and run it!. True, they 'discuss' the code in the text. But obviously that is not as good as guiding you through the process of building and deploying from scratch. As a result, you have to learn some stuff the hard way by struggling with error messages (for example how to set up library references in netbeans when creating Application Clients or how to edit the build.properties before using ant to create JMS resources etc are not mentioned)
In the preface you get a 'road map' diagram to help you 'navigate' through the tutorial. But that doesn't tell the whole story.For example the diagram doesn't really tell you that to learn about Message driven beans (which is around the in the middle of the book) you should first learn JMS( which is near the end of the book) Too many forward references makes this very difficult to use.
I am not saying it is completely useless. With a little pain and some googling you can stumble through this stuff very slowly. But it just could be an awful lot better.
Sun says they have simplified JEE so much with version 5. If that is so why can't they write a complete tutorial that readers new to JEE can read and work through step by step? The biggest criticism leveled against JEE is that it is too complex. By writing a better tutorial Sun can go a long way towards making JEE easier to use.
Rating:  - Nice Book
Thats a nice Book! the problem is this book is not portable like the java language. I sugest you to read the pdf before buy this book, so, if you like it, then purchase it. The pdf in the sun's site is equals this book, but for me is unbearable to read much time on PC.
