Metawidget is a "smart user interface widget" that populates itself, at runtime, with UI components to match the properties of your business objects. Metawidget does this without introducing new technologies. It inspects your existing back-end architecture (such as JavaBeans, existing annotations, existing XML configuration files) and creates widgets native to your existing front-end framework (such as Swing, Java Server Faces, Struts, Android). Metawidget does not replace or hide your existing UI framework and guarantees that your investment in its technology and knowledge is as valid as always.
