import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/book")
public class Book {

    @GET
    @Produces(MediaType.TEXT_XML)
    public String sayHelloXML(){
        String response = "<?xml version='1.0'?>"
                + "<hello> Hello World </hello>";
        return response;
    }

Answer 1
