WFS CORS cross proxy (Control-Allow-Origin)

[MohammedKabeer1]

Dear All,

i am trying to call WFS service in arcgis javascript and its giving me following error

XMLHttpRequest cannot load http://192.168.100.47:7001/SpatialWS-SpatialWS-context-root/xmlwfsservlet?&service=WFS&request=GetCa.... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8083' is therefore not allowed access.

here is my javascript

$(document).delegate('#wfsksaregions', 'change', function () {

         if (this.checked) {

           var opts = {

                          "url": "http://192.168.100.47:7001/SpatialWS-SpatialWS-context-root/xmlwfsservlet?",

                          "version": "1.0.0",

                          "nsLayerName": "mvdemons:wfsKsaRegions",

                          "wkid": 8307,

                          "mode": "SNAPSHOT",

                          "maxFeatures": 100,

                          "showDetails": true,

                          "infoTemplate": new InfoTemplate()             

                      };

                     _public._kabopt = opts;

                    //  esriConfig.defaults.io.proxyUrl = "localhost:8083";

                     esriConfig.defaults.io.alwaysUseProxy = false;

                     esri.config.defaults.io.corsEnabledServers.push("192.168.100.47:7001","192.168.100.47:8083");

                      var wfslayer = new WFSLayer(opts);

                      _public._kabwfslayer=wfslayer;

          alert ("hellooooooooo i am here adding WFS layer111");

          _public._kablayer = wfslayer;

            map.addLayer(wfslayer);

          //_public._kabwaterbodies.show()

         }

         else{

          alert ("hellooooooooo i am here removing WFS layer111");

          //_public._kabwaterbodies.hide()

         }

      });

please somebody reply me as soon as possible

Thanks

Is the following line pointing to your proxy file in some way?

esriConfig.defaults.io.proxyUrl = "localhost:8083";

What type of proxy are you using (PHP, JSP, DotNet)?

Thank u very much

I am using eclipse IDE

Yes if I keep this code esri.config.defaults.io.proxyUrl = ""; then its giving following error

esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.

WFSLayer.js:20 WFSLayer: Error: esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.

What I should I do to get rid of this error

Thanks

Most browsers does not support localhost for CORS requests due to same-origin policy. In order to get CORS to work in your browser for development purpose, you can set the Access-Control-Allow-Origin,Access-Control-Allow-Headers, and Access-Control-Allow-Methods values to * in your web server.

You can aslo use a domain like lvh.me (which basically points to localhost) to fool your browser as if you are requesting from a remote server.
