Hello,

I've been handed a half built GIS connector between our in house Database system and ArcGIS and have been asked to complete the project. The problem is I don't have the slightest idea how WFS and GIS systems works. So after about a week of reading up as much as I could find online I started modifying the existing code. I've got a test system but ArcMap doesn't seem to be able to find any Feature Types for the server. I've been tearing my hair out for days trying to work it out as it work in Gaia. The test wfs server is here http://wfs.wgim.com/default.aspx I've been using http://suite.opengeo.org/geoserver/wfs? as a bit of a template, since this at least works in ArpMap but I was wondering if anyone would be able to offer any assistance or guidence/general help/best practices/examples/etc.

Thanks
Ben

Ok a little red faced here. I discovered a type I was sending "<WFS_Capibilites>".

Anyway so that aside I can now see the feature list however when I select any of them I am getting Nogeometry as the name of the service.

This is exmaple of the describefeaturetype returns this

<xsd:schema xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:wgim="http://wfs.wgim.com" targetNamespace="http://wfs.wgim.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:complexType name="Anomalytype">
    <xsd:complexContent mixed="false">
      <xsd:extension base="gml:AbstractFeatureType">
        <xsd:sequence>
          <xsd:element name="AssetName" type="xsd:string" /> 
          <xsd:element name="AssetFullName" type="xsd:string" /> 
          <xsd:element name="AssetFullNamePrimary" type="xsd:string" /> 
          <xsd:element name="the_geom" type="gml:PolygonPropertyType" /> 
          <xsd:element name="DateTime" type="xsd:dateTime" /> 
          <xsd:element name="WebOverviewURL" type="xsd:anyURI" /> 
          <xsd:element name="RefNo" type="xsd:string" /> 
          <xsd:element name="AnomalyName" type="xsd:string" /> 
          <xsd:element name="AnomalyNo" type="xsd:int" />

      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
  <xsd:element name="Anomaly" substitutionGroup="gml:_Feature" type="wgim:Anomalytype" /> 
</xsd:schema>

and getFeatures return members like this

<wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs">
  <gml:featureMember xmlns:gml="http://www.opengis.net/gml">
    <wgim:Anomaly fid="Anomaly.2043" xmlns:wgim="http://wfs.wgim.com/">
      <wgim:AssetName>12" OEP</wgim:AssetName>

      <wgim:Description>Overlength freespan</wgim:Description> 
      <wgim:Comments /> 
    </wgim:Anomaly>
  </gml:featureMember>
</wfs:FeatureCollection>

And getCapabilites
