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.
Squires is a Python library which simplifies the creation of powerful self-documenting readline-based command line interfaces. Scripts using Squires have the following features in their interface: full readline bindings, tab completion of commands and their options, inline command help (which is accessed by pressing tab), option syntax validation, and hidden commands and options.
Naked Objects is an application development platform. It's called Naked Objects because all you need to develop are your domain objects; the Naked Objects platform automatically creates an object-oriented user interface (giving you the choice of different styles) and the underlying storage mechanism (again, giving you the choice as how to persist your objects).
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.
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.
The WSO2 Mashup Server is a platform for creating, deploying, and consuming Web services Mashups in the simplest fashion possible. It features support for consuming and deploying services using dynamic scripting languages, trivial deployment and redeployment, automatic and UI-based generation of Web services artifacts (e.g., wsdl, schema, policy), a set of gateways into a variety of information sources, including SOAP and POX/REST Web services, as well as plain old Web pages, and human-consumable results through a variety of user interfaces, including Web pages, portals, email, Instant Messenger services, Short Message Service (SMS), etc.
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.
