Dear Friends,
I am making a WFS Getfeature request and parsing the response of that request using GML to add a new vector layer over a particular feature of a layer. The purpose is to change the color of a one or more features in a layer So I have a WMS layer and I am making a WFS GetFeature request for getting data to create a new vector layer over a feature on the WMS layer. I have created 2 map files one for wms and other for wfs because I think a single map file cannot have both the attributes(correct me if I am wrong). My code: <html xmlns="http://www.w3.org/1999/xhtml";> <head runat="server"> <title></title> <script type="text/javascript" src="OL28/OL28/lib/OpenLayers.js"></script> <script type="text/javascript"> var mapview, layer, layer1, map, popup, latlon; var highlight_style,wfs_url; function load() { //OpenLayers.ProxyHost = "proxy.cgi?url="; var lon = 77.384; var lat = 28.389; var zoom = 9; map = new OpenLayers.Map('<%=map.ClientID%>', { controls: [ new OpenLayers.Control.PanZoom(), new OpenLayers.Control.Permalink(), new OpenLayers.Control.Navigation() ] }); // layer = new OpenLayers.Layer.WMS("OpenLayers WMS", // "http://localhost:9000/cgi-bin/mapserv.exe?";, { map: '../htdocs/Shape/newwr1rec.map', layers: 'STATE', format: 'png' }); // layer1 = new OpenLayers.Layer.WMS("Rstations", // "http://localhost:9000/cgi-bin/mapserv.exe?";, { map: '../htdocs/Shape/newwr1rec.map', transparent: true, layers: 'RailwayStations', format: 'png' }); //alert(map); layer = new OpenLayers.Layer.WMS("OpenLayers WMS", "/cgi-bin/mapserv.exe?map=C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/Delhi/Delhi1.map", { 'layers': 'Adminbndy3', transparent: false, format: "image/png" }); //map.addLayer(layer); // var defaultStyle = new OpenLayers.Style({ // 'pointRadius': 10, // 'externalGraphic': '${thumbnail}' // }); // select = new OpenLayers.Layer.Vector("Selection", { styleMap: // new OpenLayers.Style(OpenLayers.Feature.Vector.style["select"]) // }); // hover = new OpenLayers.Layer.Vector("Hover"); //map.addLayers(layer); // control = new OpenLayers.Control.GetFeature({ // protocol: OpenLayers.Protocol.WFS.fromWMSLayer(layer), // box: true, // hover: true, // multipleKey: "shiftKey", // toggleKey: "ctrlKey" // }); // control.events.register("featureselected", this, function(e) { // select.addFeatures([e.feature]); // }); // control.events.register("featureunselected", this, function(e) { // select.removeFeatures([e.feature]); // }); // control.events.register("hoverfeature", this, function(e) { // hover.addFeatures([e.feature]); // }); // control.events.register("outfeature", this, function(e) { // hover.removeFeatures([e.feature]); // }); // map.addControl(control); // control.activate(); // map.setCenter(new OpenLayers.Bounds(76.507859, 27.613907, 78.439621, 28.941223).getCenterLonLat(), 9); // define a blank Vector layer and add it to the map highlight_style = { fillColor: '#99CCFF', strokeColor: '#3399FF', fillOpacity: 0.7 }; hilites = new OpenLayers.Layer.Vector("Highlighted", { isBaseLayer: false, features: [], visibility: true, style: highlight_style } ); map.addLayer(layer, hilites); map.setCenter(new OpenLayers.LonLat(lon, lat), zoom); map.addControl(new OpenLayers.Control.LayerSwitcher()); // define the WFS server which will fill requests wfs_url = '/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/Delhi/Delhi1_wfs.map&SERVICE=WFS&VERSION=1.0.0'; } function highlightFeatures(typename, attribute, value) { alert("wfs_url :"+ wfs_url); var wfsurl = wfs_url + '&REQUEST=getfeature&typename=' + typename + '&Filter=<Filter><PropertyIsEqualTo><PropertyName>' + attribute + '</PropertyName><Literal>' + value + '</Literal></PropertyIsEqualTo></Filter>'; //alert(wfsurl); OpenLayers.loadURL(wfsurl,'',null,highlight_them); } function highlight_them(response) { // use the GML parser to turn the XML into a list of Feature objects var features = new OpenLayers.Format.GML().read(response.responseText); alert(response.responseText); // have the Vector layer purge its feature list, replace them with the new ones hilites.destroyFeatures(); hilites.addFeatures(features); hilites.setVisibility(true); } function chfeatcolor() { //alert('Hello'); highlightFeatures('Adminbndy3', 'Polygon_nm', 'Gautam Buddha Nagar'); } Now when I call the highlightFeatures() function through my code I get an error "InvalidparametersValue" -typename does not exist. so the error says that I given an invalid value for the typename parameter. As you can see I have given Adminbndy3 as the typename which is the name of the shapefile and also the wms layer. So where am I going wrong? What should I give as value for the typename paremeter? Let me know if you need the wfs mapfile. Thanks for your attention and efforts. -- View this message in context: http://n2.nabble.com/typename-error-in-WFS-GetFeature-request-tp4860968p4860968.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
