Distributed Peace of Mind.


RESTEasy is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is a fully certified and portable implementation of the JAX-RS 2.1 specification, a JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol.

RESTEasy can run in any Servlet container, but tighter integration with WildFly Application Server is also available to make the user experience nicer in that environment.
