Google Web Toolkit released

Google realeased its so called Google Web Toolkit today.

Here goes the summary –

Google Web Toolkit (GWT) is a Java development framework that lets you escape the matrix of technologies that make writing AJAX applications so difficult and error prone. With GWT, you can develop and debug AJAX applications in the Java language using the Java development tools of your choice. When you deploy your application to production, the GWT compiler to translates your Java application to browser-compliant JavaScript and HTML.

Here’s the GWT development cycle:

  1. Use your favorite Java IDE to write and debug an application in the Java language, using as many (or as few) GWT libraries as you find useful.
  2. Use GWT’s Java-to-JavaScript compiler to distill your application into a set of JavaScript and HTML files that you can serve with any web server.
  3. Confirm that your application works in each browser that you want to support, which usually takes no additional work.

The base of technology is of course, AJAX. Google has reffered to its UI components as Widgets which can be used to construct UI elements. The applications created using GWT can run in 2 modes – Hosted and Web. It is web mode which takes out soul of Java to Javascript and make Javascript & HTML combo work as Java like app running on user host. U dont need even JVM, all one need is just a GWT Java to Javascript compiler. Here is the architecture of GWT publised by Google –

Also there is a list of Featured Example Projects presented by google.

Way to go for GWT!
