help me! i hava a problem about geoprocessor. IDW and

[HuangHua]

i makes a model called Interoplation which used idw and contour tool. of course i hava changed the input type featureclass to feature dataset; and  i published it to arcgis server; but i can not use it.
this is the code, it will throw an error which is called the error cannot catched. it says "throw "Could not load cross-domain resources: ""
gp = new esri.tasks.Geoprocessor("http://172.17.70.2/ArcGIS/rest/services/Interoplation/GPServer/Interoplation");
                gp.setOutputSpatialReference({ "wkid": 4610 });
                esriConfig.defaults.io.proxyUrl = "/arcgisserver/apis/javascript/proxy/proxy.ashx";
                esriConfig.defaults.io.alwaysUseProxy = false;
                var pt1 = new esri.geometry.Point(120, 30, new esri.SpatialReference({ wkid: 4610 }));
                var pt2 = new esri.geometry.Point(120, 30.01, new esri.SpatialReference({ wkid: 4610 }));
                var pt3 = new esri.geometry.Point(120.01, 30, new esri.SpatialReference({ wkid: 4610 }));
                var arr1 = { "value": 5 }; var arr2 = { "value": 20 }; var arr3 = { "value": 18 };
//                var gr1 = new esri.Graphic(pt1, "", arr1, "");
//                var gr2 = new esri.Graphic(pt2, "", arr2, "");
//                var gr3 = new esri.Graphic(pt3, "", arr3, "");

                var gr1 = new esri.Graphic(pt1);
                var gr2 = new esri.Graphic(pt2);
                var gr3 = new esri.Graphic(pt3);
                var features = [];
                features.push(gr1); features.push(gr2); features.push(gr3);
                var featureSet = new esri.tasks.FeatureSet();
                featureSet.features = features;
                var params = {"Input_point_features":featureSet,"Z_value_field":"Id","Contour_interval":5};

                gp.execute(params);

                dojo.connect(gp, "onExecuteComplete", function (results, messages) {
                    var feature = results[0].value.features[0];
                    var symbol = new esri.symbol.SimpleFillSymbol("none", new esri.symbol.SimpleLineSymbol("dashdot", new dojo.Color([255, 0, 0]), 2), new dojo.Color([255, 255, 0, 0.25]));
                    feature.setSymbol(symbol);
                    map.graphics.add(feature);

                    query.geometry = feature.geometry;
                    queryTask.execute(query);
                    dojo.byId('messages').innerHTML = "<b>Executing Query...</b>";
                });

            }

i also use url to access the service, and also failed; it's parameter is  Input_point_features
,Z_value_field,Contour_interval;i pass the values is {"geometryType":"esriGeometryPoint","spatialReference":{"wkid":4610},"features":[{"geometry":{"x":120,"y":30},"attributes":{"Id":50}},{"geometry":{"x":119.556105,"y":26.826634},"attributes":{"Id":70}},{"geometry":{"x":122.71363,"y":25.750527},"attributes":{"Id":34}},{"geometry":{"x":123.492391,"y":28.143449},"attributes":{"Id":2}},{"geometry":{"x":124.483543,"y":30.196548},"attributes":{"Id":12}},{"geometry":{"x":124.483543,"y":30.196548},"attributes":{"Id":12}},{"geometry":{"x":124.483543,"y":30.196548},"attributes":{"Id":12}},{"geometry":{"x":125.403897,"y":26.6992},"attributes":{"Id":45}},{"geometry":{"x":118.862299,"y":32.405399},"attributes":{"Id":9}},{"geometry":{"x":115.704775,"y":29.828406},"attributes":{"Id":42}},{"geometry":{"x":115.379111,"y":27.888581},"attributes":{"Id":34}},{"geometry":{"x":114.104773,"y":30.904513},"attributes":{"Id":23}},{"geometry":{"x":114.019818,"y":32.830178},"attributes":{"Id":45}},{"geometry":{"x":114.019818,"y":32.830178},"attributes":{"Id":45}},{"geometry":{"x":120.377345,"y":33.283276},"attributes":{"Id":42}},{"geometry":{"x":125.134871,"y":34.472657},"attributes":{"Id":2}},{"geometry":{"x":121.779116,"y":35.053189},"attributes":{"Id":45}}]}; Id; 5;
and it returns error ,code 500.


anyone can help me? thank you very much!
