This is an excellent book for learning GWT, but it does assume some background knowledge in other topics, so it is not the simplest book.
I personally found that this book mentions and uses many design patterns, but if you have never studied design patterns (as a fair amount of computer scientists have not), then this book could be pretty difficult to follow.
However, if you do understand design patterns, then you will know what the author is talking about and realize that all of the sample programs and apps that are designed are truly designed well. The author shows how to use and combine great coding techniques and patterns to develop a strong application that is flexible and extensible.
Because of some of these assumptions, the textbook can be confusing, but if you do have the knowledge that is assumed, then this is an EXCELLENT textbook.
(For design patterns, I recommend the book Head First Design Patterns - it is an excellent book that covers the major design patterns and is quite enjoyable to read. You will learn all the patterns needed in that book to be able to follow GWT In Practice).
If you are looking to just make some simple apps in GWT but are not aiming for flexible, commercial level software, then you might want to look elsewhere for other textbooks. GWT In Action is much easier to follow, although it is a little dated now. However, it covers the basics of GWT which (at the time of this review) have not changed.

Repairing System With PC Repair Software
Sometimes, the computer acts strangely while being used by the user and performs tasks very slows than usually it does. It usually happens that the computer on which the user is working on catches some errors and the system crashes on critical moments with an abrupt system shutdown. Moreover, the system also takes much more time to start up and shut down than usual. Sometimes, the user has to face several critical errors like blue screen of death. It becomes very much irritating for the user to face all this.
When the system becomes full of errors, then it needs to be tuned up with proper PC repair software. The repair software checks the whole system's hard disk for any errors and repairs them accordingly. There are many kinds of errors that a system can have. An error can occur in the hard disk of the system or the memory of the system. The PC repair software scans the memory and the hard disk for the errors and warns the user of the errors that it has found in the system. The user can take care of them accordingly.
The PC repair software also checks the windows registry for any errors and fixes them. Mostly it happens that windows registry errors cause the system to act slowly and deprive them of their actual performance. The windows registry has all the entries of the programs installed in the system. When a program is uninstalled, sometimes it does not get erased from the registry and as a result of this, the system becomes slow. The PC repair software detects all these unwanted registry entries and erase them permanently to increase the performance of the computer. All in all, PC repair software cleans the system, and increases its performance by freeing the hard disk by erasing all the unwanted data and checking all the errors.
In the registry cleaner review we found that Registry Easy is the best registry cleaner for fixing the RUNDLL error.
