What other frameworks are covered in this book that support GWT.
None. The book focuses on GWT, and not much outside of that. It took 600 pages for us only do that.
Does this book have lots of examples??
and if so do you solve them using an IDE like netBeans or Eclipse?
It doesn't matter what editor you use, and we don't really use the IDE to solve problems in the book. If there was a focus on one editor though it would be Eclipse, because GWT provides some IDE support that is specific to eclipse. This includes some command line tools and the in-IDE debuging.
