java - Browser sends OPTIONS instead of PUT or DELETE -

i'm using gwt restlet , want send delete restserver. client code sending:

private void recipedeletebutton() {     string id = views.getviewrecipedetail().getrecipeid().gettext();     clientresource res = new clientresource(rest.recipe_client_resource_local + id);     res.setonresponse(new uniform() {          @override         public void handle(request request, response response) {             system.out.println(response.getstatus().getdescription());         }      });     res.delete(); } 

but when want test firefox says:

[22:28:28.796] options http://localhost:8182/recipe/35 [http/1.1 405 method not allowed 3ms]

i have found post here: browsers send options instead of post after changing http header not solve problem. post , works firefox addon resolve problem sop, there possiblity add new headers, adding put,delete , options not resolve problem..

does know solution this, in advance

edit

i have tried on serverside, still comes 405.

series<header> responseheaders = (series<header>) getresponse().getattributes().get("org.restlet.http.headers");     if (responseheaders == null) {         responseheaders = new series<header>(header.class);         responseheaders.add(new header("access-control-allow-origin", "*"));         responseheaders.add(new header("access-control-allow-methods", "get,post,put,delete,options"));         getresponse().getattributes().put("org.restlet.http.headers", responseheaders);     } 

sending option request expected behavior in case of cors request. can add handler options in restserver.

you need return valid access-control-allow-origin , access-control-allow-methods. client send second request (put or delete in case).
