    </ui>
</configuration>

* commune:  this is my layer that I want to make the symbology
* TYPE_4:this is the attribut of commune layer that specify if a town is urban or rural

also i change URL in mxml file lik that:

 thematicLayer = new ArcGISDynamicMapServiceLayer();
                        thematicLayerName = configXML.layers.layer.classificationLayerName || "commune";
                        thematicLayer.name = configXML.layers.layer.name || "Thematic layer";
                        thematicLayer.url = configXML.layers.layer.url || "http://localhost:6080/arcgis/rest/services/SOCDM/MapServer";
                        thematicLayer.proxyURL = proxyurl;
                        thematicLayer.addEventListener(LayerEvent.LOAD, thematicLayer_loadHandler, false, 0, true);

                        detailsTask.url = configXML.layers.layer.url || "http://localhost:6080/arcgis/rest/services/SOCDM/MapServer";
                        detailsTask.proxyURL = proxyurl;

in other hand in arcgis sever i'm choose:"Allow an application via the modification of the order of layers and symbology" and i add a geodabase file.

but when i comile i project and try to use this widget this error appear:"Error: HTTP request error".

any help please.Thank's
