The Google Web Toolkit (GWT) has attracted a lot of attention lately as a way to make it easier for developers to add AJAX Web 2.0 features to their applications. Like other approaches, the designers of GWT have tried to insulate developers from having to deal with the underlying JavaScript, which implements these features. GWT achieves this goal of simplifying the creation of advanced client-side JavaScript widgets by generating them from Java code.
RAP Project - FAQ Why does RAP not compile when I check out the sources? This is because some files of the Innoopract code contribution are still missing. The code contribution has been staged in two phases, and phase two is not yet finalized.
At the 2006 JavaOne event, a certain company by the name of Google (they're very big in the search market, apparently) caused quite a buzz with the shock announcement of a new open source API for developing Ajax-heavy web applications. GWT--Google Web Too
GWT is a framework developed by Google to implement AJAX technology. This framework proposes to develop the GUI entirely from Java. This code is then compiled into Javascript, to be embedded in a web application. GWT is composed of a client part, Javascript, which is the GUI application, it communicates with a server developed in Java. Past the discovery of this excellent framework, a question light in my mind: What are the correct patterns and designs code to implement this framework? Let’s take an example, look at the problems and propose improvements to emerge a coherent design. We have a Toy Project, which consists of a login screen. This example, deliberately simplistic, offers the following GUI:
The Google Web Tookit (GWT) is a cutting-edge UI framework for Java developers, which lets you create rich, interactive user interfaces using familiar idioms from Java's Abstract Window Toolkit (AWT), Swing, and the Eclipse Foundation's SWT. If you've use
The Google Web Toolkit provides the FormPanel and FileUpload classes to handle form and files submission in a rather elegant way. However, the way it works is not that straightforward when reading the API documentation. Worse, I did not find that many res
The GWT Window Manager provides a high level windowing system for the GWT applications. It offers a desktop component, dialog features , free floating windows and more. Try it by yourself and feel free to use it, it's free!

This widget displays a stack of images that you can flick through like a rolodex or a card deck. It uses gwt's deferred binding for the image generation and lightweight animation to create a fast and smooth experience in all supported browsers. Check out
Ajax4Jmx is the first open source (correct me if I am wrong) ajax enabled framework for building customized user interfaces for JMX. It is implemented with GWT, Google's Widget Toolkit.
Once you’re through with this article, there’s a followup that shows how to also make them clickable. Many people find the object-oriented aspect of JavaScript to be very confusing. Fortunately, the designers of the Google Maps API have managed to ma
First I must admit that I don't buy GWT's approach. There is a reason why we don't write HTML code from servlets anymore. Programmers usually are bad UI designers (look at my website for something to back my claim ;-) and great UI designers usually don't
I have been using Wicket for a while now and I’ve occasionally wondered if GWT provides any kind of advantage over Wicket. Here is a comparison and instead of coding a simple “Hello World” kind of example, here is something a little more complex. Functionality The target functionality is a one-page application that shows data in a single table. Item counts are displayed categorized under multiple “spaces” (workspaces). There is a summary row. The user can click on a space to expand the count of items grouped by status. Some of the tricky parts are: * The number and names of the possible status types can be different for different spaces. * Some of the table cells have to be merged to represent the grouping by space and then by status. * the style / color of the different cells has to be controlled to differentiate the total count from that grouped by status. Let's look at the Java code common to the GWT and Wicket implementations.
