Web developers already know they can use Ajax to add rich, user-friendly,

dynamic features to their applications. With the Google Web Toolkit (GWT), a

new Ajax tool from Google that automatically converts Java to JavaScript, they

can build Ajax applications using the Java language. GWT lets developers focus

on application design and functionality, rather than on browser differences, and

allows them to re-use code throughout the layers of their applications.

GWT in Practice

is an example-driven, code-rich book designed for web developers

who have already learned the basics of GWT. After a quick review of

GWT fundamentals, GWT in Practice presents scores of handy, reusable

solutions to the problems developers face when they need to move beyond

“Hello World” and “proof of concept” applications. This book skips the theory

and looks at the way things really work when developers are building projects

in GWT.

The Market:

The GWT approach of using a static language to create cross browser compatible

code is becoming very popular even beyond Java and GWT. There is a

Microsoft effort to do the same using C#, along with Python and Ruby variants.

Based on mailing list activity, Java User Group focus and “buzz,” GWT itself is

rapidly increasing in popularity. Java developers love using Java rather than

JavaScript to build Ajax applications. This feature alone promises to make GWT

a widely used tool for Java developers.
