Ajax programming using GWT.

GWT - google web toolkit basically lets you code Ajax capable web applications. GWT is basically a front end, serving as the User Interface for web Application. It can easily be integrated with servlets as backend. The remote proceedure call (RPC) included in the toolkit is also quite easy to use.

As compared to other offerings like dojo and QooxDoo, GWT is written in JAVA. This means a web developer may not know a thing about javascript and still be able to code AJAX applications. This is also convenient as servlets are also written in JAVA.


To start, download the latest Java SDK here.

You will also need Java capable IDE. You may use either Eclipse or Net beans.
If you use netbeans, you will also need this plugin. (this also containes a good tutorial on GWT)

Then download the latest GWT available here. In this writting, 1.2 is the latest released version.

Install all components then you are all set to write your first GWT application.
