Google Web Toolkit (GWT)

Course:  GWT1
Duration:  2 Days
Level:  I
Course Summary

This course teaches students how to create Web front-ends using the GWT. The student will learn how to create web pages using GWT widgets using Java, Eclipse, and CSS. In addition, command line project creation and testing of GWT applications is included. Starting with code development through compiling Java artifacts into optimized JavaScript for all major browsers is demonstrated in practical workshops. This course provides a foundation in developing front-end modules with GWT widgets, panels, events and other facilities provided by Google. Debugging and performance considerations are also addressed.
