Announcement: Resteasy 3.0.19.Final is available.
RESTEasy is a fully certified and portable implementation of the JAX-RS 2.0 specification, a JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol. It is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications.It can run in any Servlet container, but tighter integration with the JBoss Application Server is also available to make the user experience nicer in that environment
