Advanced 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 course explores advanced GWT features from user interface widgets to client-server integration. First, students will learn how to create and use GWT modules. From there, they will explore many advanced user interface widgets and panels. Then they will learn how to apply styles to GWT widgets with CSS. Next, students will learn to create their own composite widgets. JUnit testing is the focus of the next chapter, followed by a chapter on the GWT Java Emulator. Students will then learn about various connectivity and integration features of GWT as well as how to invoke native JSNI methods. Finally, the course ends with a chapter on GWT best practices.

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

Prerequisites: GWT and 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.
