Tabula is comprised of several subprojects, such as a server and GUI tools.
The framework is based on SOFEA, removing the UI responsibilities from the server to other applications. The server itself deals with business logic and persistence, among other issues. In order to expose this functionality, there is a REST service layer, implemented with the RESTlet library. I've created a simple XML format specification to declare and configure the services, allowing for runtime changes. The implementation supports Java and Groovy classes as request handlers.

The main goal of the framework is to reduce app restarts during development as much as possible, while providing a simple environment for prototyping and developing small to medium applications.
