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 specification. JAX-RS is a new 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 the JBoss Application Server is also available to make the user experience nicer in that environment.


  • Fully certified JAX-RS implementation
  • Portable to any app-server/Tomcat that runs on JDK 6 or higher
  • Embeddedable server implementation for junit testing
  • Client framework that leverages JAX-RS annotations so that you can write HTTP clients easily (JAX-RS only defines server bindings)
  • Client "Browser" cache. Supports HTTP 1.1 caching semantics including cache revalidation
  • Server in-memory cache. Local response cache. Automatically handles ETag generation and cache revalidation
  • Rich set of providers for: XML, JSON, YAML, Fastinfoset, Multipart, XOP, Atom, etc.
  • JAXB marshalling into XML, JSON, Jackson, Fastinfoset, and Atom as well as wrappers for maps, arrays, lists, and sets of JAXB Objects.
  • GZIP content-encoding. Automatic GZIP compression/decompression suppport in client and server frameworks
  • Asynchronous HTTP (Comet) abstractions for JBoss Web, Tomcat 6, and Servlet 3.0
  • Asynchronous Job Service.
  • Rich interceptor model.
  • OAuth2 and Distributed SSO with JBoss AS7
  • Digital Signature and encryption support with S/MIME and DOSETA
  • EJB, Seam, Guice, Spring, and Spring MVC integration
