DynaSpring is a dynamic, extensible DSL (Domain Specific Language) tailored for building a Spring Application Context. Like Spring/XML, it is a declarative, tree-structured language; but, unlike XML, it supports all the kinds of abstractions found in common programming languages: conditional evaluation, iteration, definition of functions and variables, etc. DynaSpring also offers a set of utilities that make working with Spring easier and that build upon Spring to give you even more options in structuring your enterprise application.

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.

VRaptor3 is a fully-fledged Java Web framework focused on fast development and maintainable code. It intends to make RESTful application development easy.
