i have restful server , jquery script calling data. not able data via jsonp.

java method:-

@get   @path("search") @jsonp(queryparam="callback") @produces({"application/x-javascript"}) public response getalltestdata(@queryparam("callback") string callback) {             system.out.println("i got executed!");         string result="{\"id\":1}";     //return response.status(200).entity("{ foo: 'bar' }").build();         //return result;         return response.ok("{status: 'success'}").header("access-control-allow-origin", "*").build();     } 

jquery script:-

$("button").click(function() {    var surl =  "http://localhost:8080/wikirating/engine/employee/search";    $.ajax({       type: 'get',        url: surl,        data: {"name": 1},        datatype: "jsonp",        jsonp : "callback",        jsonpcallback: "jsonpcallback",        success: function(json) {                    alert("success");                 },                 error: function(e) {                    alert("error");                 }        }); }); 

i using apache tomcat v7.0

web.xml

i think have set headers does't seem work , error fired , alert("error"); executed.

also script running on port 80 while tomcat server running on port 8080 .

thanking in advance.
