WidgetServer is a component based, server-side, Java/XML rich-client-framework.
Editor: WidgetServer is a component based, server-side, Java/XML rich-client-framework which enables an application to run as either:

- an application with a rich Web client based on AJAX (HTML, XML, CSS, JavaScript)
- an application with a simple Web client based on HTML and CSS
- a standalone application with a Swing GUI,
- a client/server application with a thin Swing client,
- or a mobile application on different devices like PDAs or Smartphones

without any change and without loss of functionality!
WidgetServer gives you the choice if you develop a GUI either using

- HTML Markup templates,
- a Java API like Swing,
- XML markup
- or any Combination.

WidgetServer provides a clean, object-oriented Java programming interface for Web and Swing GUIs. The framework prevents from struggling with browser specific HTML, JavaScript and HTTP requests or from caring about the internals of Swing.
For Swing client/server applications the framework handels the client/server split by using the half-object pattern. Client/server communication including compression and security is covered by the framework also.
Web applications are completely and transparentely AJAX enabled, while the use of this feature remains fully configurable.
A Multi-Channel-Mode enables one server to serve Swing clients and Web clients at the same time.
The framework also covers areas of data-binding, persistence, threading and synchronisation.
The project comes with a WYSIWYG GUI-builder which is completely built on the WidgetServer framework technology. you can free download WidgetServer 2.9 now.
