Awake File is a framework that allows Android and Java Desktop developers to very easily implement file uploads and downloads through HTTP. Security has been taken into account from the design stage: server side configuration allows you to specify strong security rules in order to protect the files. It allows listing, creation, and deletion of remote directories, calling of remote Java methods, and displays nice progress indicators to your users.
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.
