VRaptor3 is a fully-fledged Java Web framework focused on fast development and maintainable code. It intends to make RESTful application development easy. A resource corresponds to a business logic annotated with its path and HTTP method. It runs inside DI Containers (Spring or Pico out of the box) and, therefore, enables full integration with them. Also, using Hibernate is easier: its session is automatically injected by VRaptor, so you just have to use it. VRaptor3 is refactor-friendly, especially in its redirecting configuration. It is also nicely extensible.
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.
