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.
Perf4CDI is an add-on package for implementations of CDI (Contexts and Dependency Injection for the Java EE platform, also known as JSR-299) providing convenient integration with Perf4j, a performance monitoring library for Java applications. For basic usage, it's enough to annotate the profiling method in CDI-based applications. Many settings can be customized.
