VRaptor
VRaptor is a Java MVC Framework focused in delivering high productivity to web developers. The framework is strongly based in the best development practices such as Inversion of Control (achieved through Dependency Injection) and Convention Over Configuration.
The version 3 of the framework was based on Dependency Injection containers such as Spring IoC or Guice (the developer could choose between different options). This release was a major success, with more than 60 thousand downloads, mainly in Brazil. Since the version 4, VRaptor is based on CDI and is completely integrated with Java EE 7 application servers.
