RESTEasy

RESTEasy is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It strives to be standards based wherever possible, but to also innovate when appropriate.

RESTEasy implements the JAX-RS specification. JAX-RS, JSR-311, is a new JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol. Resteasy is an portable implementation of this specification which can run in any Servlet container. Tighter integration with JBoss Application Server is also available to make the user experience nicer in that environment. While JAX-RS is only a server-side specification, Resteasy has innovated to bring JAX-RS to the client through the RESTEasy JAX-RS Client Framework. This client-side framework allows you to map outgoing HTTP requests to remote servers using JAX-RS annotations and interface proxies.

Features

• JAX-RS implementation
• Portable to any app-server/Tomcat that runs on JDK 5 or higher
• Embeddedable server implementation for junit testing
• Rich set of providers for: XML, JSON, YAML, Fastinfoset, Atom, etc.
• JAXB marshalling into XML, JSON, Fastinfoset, and Atom as well as wrappers for arrays, lists, and sets of JAXB Objects.
• Asynchronous HTTP (Comet) abstractions for JBoss Web, Tomcat 6, and Servlet 3.0
• EJB, Spring, and Spring MVC integration
• Client framework that leverages JAX-RS annotations so that you can write HTTP clients easily (JAX-RS only define server bindings)
