Depending on your container version, Jersey (or any other JAX-RS implementation) will still use a Servlet for dispatching requests to the appropriate handler.

Also, don't confuse XML or JSON with REST. You will get these for free in most (if not all) JAX-RS implementations, but these implementations still delegate content marshalling to other libraries (e.g. JAXB).
