GWT Training

Workshop Length

5 days

Objective

Learn to build non-trivial AJAX applications using GWT.

Description

GWT is one of the most exciting web development technologies available today. And GWT is now our most popular workshop. Our current GWT workshop covers GWT 2.4.

Smart Soft has been using and teaching GWT since before it's 1.0 release and we were the first to offer GWT training back 2006. We now have a over a dozen real-world GWT applications under our belt and this workshop is based on that experience.

In this workshop we cover all of the nuts and bolts of GWT (the widget library, history support, etc.) but we also place a strong emphasis on GWT best-practices and patterns.

Our public workshops are usually small (2 or 3 students) and tailored to meet the specific needs of each student. So if there are special topics you would like us to cover please let us know.
