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.
Google Gadgets for Linux provides a platform for running Google Gadgets under Linux, catering to the unique needs of Linux users. It's compatible with the gadgets written for Google Desktop for Windows as well as the Universal Gadgets on iGoogle. There are two main components to the application: one is a common gadget library responsible for running and presenting a gadget, and the other is a host program that allows the user to choose gadgets and run them on the desktop. Currently it has hosts written for GTK+ and Qt, with the GTK+ host offering a sidebar similiar to that of Google Desktop for Windows.
Swing has lot of components built in, but still some are missing. This project provides the developer community with these missing components, inspired from modern user interfaces. It provides a PropertySheet component, a collapsible task pane (JTaskPane), a button bar (JButtonBar), a font chooser (JFontChooser), an Outlook Bar (JOutlookBar), a Tip Of The Day dialog (JTipOfTheDay), and a directory chooser (JDirectoryChooser).
Tapestry Palette is a plugin for Eclipse that builds upon the Spindle plugin. The palette provides a tree view of Tapestry component libraries, a component inspector to discover parameters available with links to HTML documentation, drag and drop addition of Tapestry component references to templates, and a Property Sheet for editing of component bindings. The plugin can be installed from within Eclipse via an update site.
JewelCLI provides an API to parse command line arguments. It uses Java annotations to present a very simple but powerful interface. Options are defined using an annotated Java interface definition. This allow a declarative style which can be much clearer than the procedural style used by some other Java CLI libraries.
Wicket Web Beans (WWB) is an Apache Wicket component toolkit for displaying and editing POJOs that conform to the JavaBeans specification. Web pages are automatically generated based on bean properties and certain conventions. If necessary, the layout, editability, and actions of these pages can be customized on an exception basis. In other words, the toolkit normally does what you'd expect, but when it doesn't, you can override its behavior.
IT Mill Toolkit is a server-side RIA (Rich Internet Application) library that provides a versatile set of AJAX widgets for Java programmers. Applications are programmed in Java and executed server-side. At the client-side (i.e. in the browser), enhanced GWT widgets are used for presentation.
