RESTEasy is a JBoss project that helps build RESTful Java applications by implementing the JAX-RS 2.0 specification. It provides a portable implementation that can run in any servlet container. RESTEasy supports content negotiation and includes annotations like @Path, @GET and @POST to define RESTful resources. It also features rich providers for XML, JSON and other data formats and integrates with frameworks like EJB, Seam and Spring.
