XUI is a Java and XML platform for building Rich Internet Applications. The platform greatly reduces the amount of code needed to build feature rich applications on a wide range of systems. The project includes plug-ins for both NetBeans and Eclipse, plus support for AWT, Swing, SWT, J#, and HTML.
Wicket is a Java Web application framework implementing simplicity, separation of concerns, and ease of development. Wicket pages can be mocked up, previewed, and later revised using standard WYSIWYG HTML design tools. Dynamic content processing and form handling is all handled in Java code using a component model backed by POJO data beans that can easily be persisted using your favourite technology.
WidgetServer is a Java/XML server-side GUI-framework which enables an application to run as either a monolithic Swing app, a client/server Swing app, or as a Web app without any change and without loss of functionality. An Eclipse Plugin is available as well. A rich widget set is supported that includes tree views, tabbed panes, split panels, and much more. Animations, all types of events, and several effects are supported, as well. A unified widget-based, object-oriented programming interface for Web and Swing GUIs is offered to the developer to control and assemble the GUI. Web applications are fully AJAX enabled. For Swing client/server applications, the framework handles client/server communication, including compression and security layers.
JChart2D is a Swing widget for precise runtime visualization of numerical tuples in an x-y plot. It is easy to use and is designed for runtime display. Unlike other charting tools that cover all kinds of views (pie, bar, etc.), it just creates precise x-y plots. It is thread-safe: many different threads in an application may each add data to plot. A single chart may contain multiple different traces. It also features automatic scaling, choice of unit, viewports (zooming), output to images (PNG, JPEG, and EPS), logarithmic axis, and custom rendering of datapoints (lines, dots, discs, and filled polygons).
