The Google Web Toolkit is a powerful framework for developing Rich Internet Applications (RIA) that need to communicate with a server to provide a responsive web application. The library contains a large set of standard graphical elements ('widgets'), and there is also the capability to create and re-use your own customised ones. Advanced features, such as Internationalisation are supported. The framework allows JUnit testing.

The framework works by generating JavaScript code directly from server-side Java, and inserting this into the returned HTML pages, (via a JS optimising process). It is possible in GWT to interact with this process, and develop with JavaScript directly.

Target Audience:

The course is designed for web developers who intend to use the Google Web Toolkit to write Rich Internet Applications with a Java-based framework.

  • Delegates must have some Java Programming skills
  • Awareness of Web technologies (e.g. HTML) would be highly beneficial

At the end of this course you will be able to:

  • Understand the Google Web Toolkit architecture
  • Write, deploy and test GWT applications
  • Use supplied GWT widgets and create new custom widgets
  • Use GWT for rich internet applications, invoking AJAX
