Restlet is a framework that brings the simplicity and efficiency of the REST architectural style to Java developers.

Restlet project is composed of two parts, a neutral API and a reference implementation (Noelios Restlet Engine). It supports all REST concepts (resource, representation, data, connector, components, etc.) and is suitable for both client and server REST applications.

The server connectors provided are HTTP (via Mortbay's Jetty or an adapter Servlet) and the client connectors are HTTP, JDBC, and SMTP (via JavaMail).
