Introduction to GWT


Duration: 4 days

Method: Instructor led, Hands-on workshops

Price: $2250.00

Course Code: GG1005


Experienced Java developers looking to adopt GWT and GWT-Ext


The Introduction to GWT training course examines the ins-and-outs of developing web applications using the GWT framework.

The Google Web Toolkit training course begins with a review of web application concepts and technologies, like JavaScript, JSPs, etc. It then examines the architecture of a common GWT application, in terms of functionality, separation of concern, and component modularization. With the foundation laid, the course then examines the GWT framework and concludes with an exploration of GWT-Ext.


Upon successful completion of this course, the student will be able to:

  • Understand the origins of GWT, what GWT does, and how it addressed the challenges of building AJAX applications
  • Learn about GWT’s infrastructure, project setup and code artifacts
  • Learn to use GWT’s predefined widgets – controls and containers
  • Implement GWT events and handlers to build interactive applications
  • Learn how to style GWT widgets with CSS and how to manage styles
  • Learn how to make composite widgets
  • Built a GWT-based application
