Restlet is a lightweight REST framework for Java. The project is composed of two parts, the Restlet API (alternative to Servlet 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(S), AJP (via Mortbay's Jetty or an adapter Servlet) and the client connectors are HTTP(S), File, JDBC, and SMTP(S).
Fourteen bugs were fixed since the 1.0.1 release. Jetty was updated to version 6.1.4. The content negotiation algorithm was updated in order to give precedence to the default language set by the server over the "All languages" preference.
