**Summary** *GWT in Action, Second Edition* is a completely revised edition of the best-selling GWT book. It covers the new features introduced in GWT 2.4 and 2.5, as well as the best development practices that have emerged in the GWT community. It begins with a rapid-fire introduction to GWT and Ajax to get you up to speed with GWT concepts and tools. Then, you’ll explore key concepts like managing events, interacting with the server, creating UI components, building your user interface declaratively using UiBinder … and more. **About the Technology** Google Web Toolkit works on a simple idea. Write your web application in Java, and GWT crosscompiles it into JavaScript. It is open source, supported by Google, and version 2.5 now includes a library of high-quality interface components and productivity tools that make using GWT a snap. The JavaScript it produces is really good. **About this Book** *GWT in Action, Second Edition* is a revised edition of the best-selling GWT book.
