There have been a steady stream of GWT books coming out in the last few months and there are a number of others that are almost ready to go to press. Could you explain a little bit about your book and what differentiates it from the others? What is your focus or approach to GWT?
Also, I'm particularly interested in integrating GWT with other Java technologies like the the Java Persistence API and web services. Is this something that your book covers?
The focus of my book is to get users up and running with GWT as quickly as possible. It is an immersion approach or learn by doing things with it, as opposed to the analytical approach - learn how it all works in excruciating detail before you try to use it. I find myself always gravitating towards the immersion approach, and this book reflects that :-)
I go through the samples fairly quickly and by the end of the book you should have a good grasp of this framework and the complete life cycle of development using it. I dont delve deeply into the internals of GWT or how it all works under the proverbial GWT hood. As far as integration goes, I dont not cover integrating with hibernate. The yahoo weather widget uses Yahoo's weather service to get the info on the backend.
Thanks for the overview of your book. That gives me a good idea what to expect in it. I also learn better by immersion. I find that I quickly abandon many analytical books in favor of examples that get my feet wet. Thank you and good luck with your book.
GWT also does a lot of framwork piping for you. It handles bookmarking, back buttons and a lot more.
As for web services, it can be used with them just like any other web application framework. Content is often obtained through web services and then used to updatedynamic page content.
