Google Web Toolkit Tutorial
(5 pages, 166 kb, pdf format)

Learn to write AJAX applications from Java classes, using the new development paradigm introduced by this new Google framework. Recently, the 1.20 version of Google Web Toolkit (GWT) was released. This framework introduces a new AJAX application development paradigm. Is goal is to
hide from programmer the JavaScript code implementation, considering this job is repetitive, error-prone and full of tedious tasks, like browser incompatibility handling. GWT abstracts JavaScript using a Java class library, where a visual AJAX components (the widgets) library is available. These components are well known by GMail and Google Maps users. This tutorial presents how GWT changes the application development paradigm, and brings an implementation sample using the framework.
