Google Web Toolkit - Gufran Mohammed

What is Google Web Toolkit ? Google Web Toolkit (GWT) is an open source Java software development framework that makes writing AJAX applications easy for developers who don't speak browser scripts as a second language. With GWT, you can develop and debug AJAX applications in the Java language. Write your front end in the Java programming language,and the GWT compiler converts your Java classes to browser-compliant Java Script and HTML.

GWT development cycle Develop a front end application in Java Programming language using any Java IDE and GWT libraries GWT's Java-to-JavaScript compiler converts your application into a set of JavaScript and HTML files that can be served with any web server. Confirm that the application works in each browser

Why GWT? You can use all of your favorite Java development tools (Eclipse, IntelliJ, JProfiler, JUnit) for AJAX development. Static type checking in the Java language boosts productivity while reducing errors. Common Javascript errors (typos, type mismatches) are easily caught at compile time rather than by users at runtime. Code prompting/completion is widely available. Java-based OO designs are easier to communicate and understand, thus making your AJAX code base more comprehensible with less documentation.

Debugging and Deploying GWT Applications GWT applications can be run in 2 modes: Hosted Mode Web Mode

Google Web Toolkit Architecture GWT has four major components: Java-to-Javascript compiler "Hosted" web browser Two Java class libraries (JRE Emulation library and GWT web UI class library)‏

Google Web Toolkit Features Browser compatible (IE, Firefox, Mozilla, Safari, and Opera)‏ Internationalization Browser history management Dynamic, reusable UI components Really simple RPC Real debugging Completely Open Source Interoperability
