GWT short for Google Web Development Kit lets programmers to develop Ajax web applications with java. Java codes are converted in to JavaScript and html codes by the GWT compiler. GWT applications are called modules and modules are described using a xml file, assuming the module name as "mymodule" name of the xml file would be "mymodule.gwt.xml".
