Call Ajax Play FrameWork - playframework-2.1

Question

I have a problem with ajax, play framework 2.1.1:
My Play Project
routes:
POST /sample/testapi controllers.Application.testapi()
GET /sample/ajax controllers.Application.ajax()
Application.java
public static Result testapi() {
DynamicForm dynamicForm = DynamicForm.form().bindFromRequest();
String data= dynamicForm.get("data");
Logger.debug(data);
return ok("<user no='1'><id>1</id><name>Peter</name></user>");
}
public static Result ajax() {
return ok(ajax.render());
}
When I call action "testapi" from ajax.scala.html through ajax
My ajax code
$.ajax({
url : "http:// localhost:3333/sample/testapi",
type: 'POST',
data: {data: "test"},
dataType: "text",
success : function(result) {
alert(result);
},
error : function(request,error) {
alert(error);
}
});
It working fine.
And I have a html file and I call to play project through ajax.
The action had been called, but not return result and show alert "error".
Please help me. Thanks.

Answer 1

I added "response().setHeader("Access-Control-Allow-Origin", "*");" to my action.
public static Result testapi() {
response().setHeader("Access-Control-Allow-Origin", "*");
DynamicForm dynamicForm = DynamicForm.form().bindFromRequest();
String data= dynamicForm.get("data");
Logger.debug(data);
return ok("<user no='1'><id>1</id><name>Peter</name></user>");
}
"response().setHeader("Access-Control-Allow-Origin", "*");" allow other domain call it.
