Introduction to GWT Training Class Summary

Google Web Toolkit (GWT) allows Java developers to create Web 2.0-ready Ajax front ends. GWT compiles these Java artifacts into optimized JavaScript for all major browsers. This intensive, hands-on training course provides students a foundation in developing front-end modules with GWT widgets, panels, and events. Students will also learn how to work with images and client bundles as well as how to incorporate history and bookmarks in their Ajax applications. The course continues with a chapter on GWT Utility classes that make it easy to work with cookies, animation, file uploads, and timers. The course ends with coverage of GWT’s remote procedure call mechanism.

Audience: Java developers who wish to quickly get to create Ajax application with the Google Web Toolkit.

Prerequisites: Java programming experience is required. Basic knowledge of HTML, CSS, and JavaScript is recommended. Previous experience doing widget-based Form development using events as well as HTTP exposure is beneficial.

Class Length: 3 days
