Introduction to the Google Web Toolkit Framework

Google Web Toolkit (GWT) is an open source web development framework that allows
developers to easily create high-performance AJAX applications using Java. With GWT, you
are able to write your front end in Java, and it compiles your source code into highly optimized,
browser-compliant JavaScript and HTML. “Writing web apps today is a tedious and error-prone
process. You spend 90% of your time working around browser quirks, and JavaScript’s lack
of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
It doesn’t have to be that way,” reads the Google
Web Toolkit site

In this tutorial, you learn how the above principles are applied to real applications. At
the same time, you are introduced to NetBeans IDE’s support for GWT and you build a simple
application that makes use of some of these features.


Content on this page applies to NetBeans IDE 6.x
