CXF supports the Java API for RESTful Web Services: parts of JAX-RS 2.0 (JSR-339) and fully JAX-RS 1.1 (JSR-311). CXF 2.7.0 supports most of the new features introduced in JAX-RS 2.0, excluding the client API, but note that the CXF client API has been retrofitted to support new filters, interceptors, exception classes and Response API, plus the asynchronous client invoker API.
You are encouraged to read the JAX-RS specification to find out information not covered by this documentation. The specification introduces such terms as root resources, resource methods, sub-resources and sub-resource locators, message body readers and writers, and contexts. Also check the CXF JAX-RS documentation for an up-to-date guide on new features and improvements. This section provides an overview of the JAX-RS specification and API.
