Writing dynamic web applications today is a tedious and error-prone process; the developer spends 90% of his time working around subtle incompatibilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
GWT lets the user use standards compliant tools for writing web apps.
Write the front end in the Java programming language, and the GWT compiler converts the Java classes to browser-compliant JavaScript and HTML.
Here are some key features of "Google Web Toolkit":
· Dynamic, reusable UI components
· Really simple RPC
· Browser history management
· Real debugging
· Browser compatible
· JUnit integration
· Internationalization
· Easily create efficient internationalized applications and libraries. Interoperability and fine-grained control.
· Google API Library: Google Gears support
What's New in This Release: [ read full changelog ]
General Enhancements:
· App Engine tools for Android: Build installable Android apps that rely on App Engine for server-side support.
· Incremental RPC Tooling: Add server-side methods to App Engine code and GPE will generate the necessary serialization and Android code on the fly.
· Apps Marketplace Support: Deploy apps to the Google Apps Marketplace as easily as to App Engine.
· UI Designer: Faster startup and editing times, split-mode editing support for UiBinder, simplified CSS property editing, UiBinder morphing, IsWidget support, and more.
· Persistent Unit Cache: GWT Compiler and Development mode now cache compilation artifacts between runs. This results in faster startup time for iterative development.
· Scrolling DataGrid (#188): The new DataGrid widget supports vertical scrolling with a fixed header (above) and footer (below).
· Design Time Support (#226): The Beans.isDesignTime() method was added to the GWT emulation library in order to better isolate runtime-only code when a UI is edited in the UI Designer.
Noteworthy Fixed Issues:
· Polymorphism not supported by RequestFactory.
· Support RequestFactory service inheritance on the client.
· ListEditor subeditors' value is not flushed when used with a RequestFactoryEditorDriver.
· Memory-leak in pure-Java's c.g.g.core.client.impl.WeakMapping.
· GWT compiler dropping clinits.
· Make RequestFactory type tokens more compact.
· Editor framework does not support is / has methods.
