jax-rs vs HttpServlet in jee [duplicate]

which one is better for implementing restful architecture?

jax-rs example :

 @GET @Produces(MediaType.TEXT_XML) public String sayXMLHello() { return xmlHello(); } 

servlet example :

 protected void doGet( HttpServletRequest request , HttpServletResponse response ) throws ServletException , IOException { //showUsers( response); } 

UPDATE:

I can't DELETE THIS QUESTION... Please do not give me a negative rating... thanks.

And so, I prefer to use servlet for implementing the restful... Because of making easy and flexible designs...
