Description
|
|
If you are used to some of the newer Web 2.0 sites like google maps, gmail,
etc., you must have noticed the fast reponse and the dynamic page
refreshing facilitated by AJAX techniques. Google has been in the forefront
in promoting these techniques to common applications.
There are already many toolkits in the Ajax world. Dojo, JQuery, YUI, etc.
are examples of some of these based on JavaScript libraries. GWT was one of
the early toolkits that took a radically different approach. By using Java
as the development language, Google was able to leverage the wealth of
mature tools and developer base already available.
After looking at how Ajax works, this course will cover the techniques,
components, and tools used for building GWT applications.
About 70% of the time will be spent on hands-on labs.
