RequestPermissionException: URL is invalid or violates the same-origin security restriction

[Vrushali Patil]

Hi,

Can anyone help I am getting this error. And I have gone through all the
older posts but not able to resolve. I am trying to send request to Tomcat
server to get "SOS" data from a WAR file "52nSOSv3_WAR"

Error:

com.google.gwt.http.client.RequestPermissionException: The URL
http://localhost:8080/52nSOSv3_WAR/sos is invalid or violates the
same-origin security restriction

My code is

        url = "http://localhost:8080/52nSOSv3_WAR/sos";;
        requestquery = "REQUEST=GetCapabilities";
        StringBuffer posturl = new StringBuffer();
        posturl.append(URL.encode(url));

        StringBuffer postquery = new StringBuffer();
        postquery.append(URL.encode(requestquery));

        RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
posturl.toString());
        builder.setHeader("Content-Type","text/xml");

            builder.sendRequest(postquery.toString(), new RequestCallback()
{
            public void onError(Request request, Throwable exception) {
              // code omitted for clarity
                System.out.println(exception.getCause().toString());
            }

            @Override
            public void onResponseReceived(Request request,Response
response) {
                // TODO Auto-generated method stub
                String var = "";
                var = response.getText();
                System.out.println("This is response");
                System.out.println(var);

            }
          });



    }
