How to set content type dinamically?
    @GET
    @Produces({"application/xml","text/html","text/plain"})
    public Response get(...) {
        Response.ok(something).type(?).build();
    }
Any solution without split method and use @Produces with single type? => 
It's ugly...
    @GET
    @Produces("application/xml")
    public Response getXML(...) {
        Response.ok(something).type("application/xml").build();
    }
    @GET
    @Produces("text/html")
    public Response getHTML() {
        Response.ok(something).type("text/html").build();
    }
    @GET
    @Produces("text/plain")
    public Response getTEXT() {
        Response.ok(something).type("text/plain").build();
    }
Can get the "default" contentType selected by Jersey on my method?
     Please note that Jersey (and any JAX-RS implementation) calculates 
the content type to invoke the method with valid media type...
