WFS request failed

Hello,
We are working on ArcGIS server 9.3 Enterprise Basic version, where we have published a Geodata service with WFS capability enabled. Using WFS capability, we want to do spatial selection of features based on the GML polygon geometry described in the OGC filter. Here is the typical request XML (which is failing with the response provided below):

WFS Request XML:

<wfs:GetFeature version="1.1.0" service="WFS" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml" xmlns="http://www.opengis.net/wfs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs http://appolo/wfsconnector/schema/wfs/1.0.0/WFS-capabilities.xsd">

        </gml:Polygon>
      </ogc:Intersects>
    </ogc:Filter>
</wfs:Query>
</wfs:GetFeature>

WFS Response XML:

<ows:ExceptionReport version='1.1.0' language='en' xmlns:ows='http://www.opengis.net/ows'>
<ows:Exception exceptionCode='InvalidParameterValue'>
    <ows:ExceptionText>Wrong coordinates.
    </ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

Any help / hint would be appreciated.

From the error, it looks like there is some issue with the geometry/coordinates included in the request.

WFS version 1.1.0 uses the traditional axis order for geographic and cartographic systems as latitude/longitude (y/x), so switching the order of coordinates in your request may fix it.

<gml:coordinates>
6478332.323,484124.936 6478332.323,485002.284 6479035.891,485002.284 6479035.891,484128.556 6478332.323,484124.936
</gml:coordinates>

Hi,

It looks like you formed a WFS 1.1.0 request with GML2 in the filter, which is invalid, instead you should use the GML3, see sample below:

<wfs:GetFeature
     service = 'WFS' 
     version = '1.1.0' 
     xmlns:wfs = 'http://www.opengis.net/wfs' 
     xmlns:ogc = 'http://www.opengis.net/ogc'

     xmlns:esri = 'http://www.esri.com' 
     xmlns:xsi = 'http://www.w3.org/2001/XMLSchema-instance' 
     xsi:schemaLocation='http://www.opengis.net/wfs ../wfs/1.1.0/WFS.xsd'> 
     <wfs:Query typeName='highways' srsName="urn:ogc:def:crs:EPSG:6.9:4326">
      <ogc:Filter>

Thanks,
