[OpenLayers-Users] Working with Openlayers.Layer.Vector and WFS

[Eduardo Ramos]

Well, thanks for the quick response.

The WFS response to
'http://localhost:2006/GetFeature.ashx?service=WFS&version=1.0.0&request=GetCapabilities'
is:

<WFS_Capabilities xsi:schemaLocation="http://www.opengis.net/wfs

I've made some changes in the request, namely the version and featureNS, and
now it looks like this:

var layer = new OpenLayers.Layer.Vector("Guybrush Threepwood", {
                 strategies: [new OpenLayers.Strategy.BBOX()],
                 protocol: new OpenLayers.Protocol.WFS({
                     version: "1.0.0",
                     url: "http://localhost:2006/GetFeature.ashx",
                     featureType: "MonkeyIsland",
                     featureNS: "http://www.opengis.net/wfs/",
                     geometryName: "VL_GMTR",
                     srsName: "EPSG:4326"
                 }),
                 projection: new OpenLayers.Projection("EPSG:4326")
             });

             map.addLayer(layer);


By the way, my WFS server has the following Features:

http://localhost:2006/GetFeature.ashx?service=WFS&version=1.0.0&request=DescribeFeatureType

<schema targetNamespace="http://www.mapinfo.com/wfs"
elementFormDefault="qualified">
  <xs:import namespace="http://www.opengis.net/wfs"

          <xs:element name="VL_GMTR" minOccurs="0" maxOccurs="1">
            <xs:complexType>

              </xs:sequence>

          </xs:element>
          <xs:element name="ROWID" nillable="true" type="xs:string"
minOccurs="0" maxOccurs="1"/>
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>
</schema>

Thank you

Edu
