[Geoserver-users] Problems with WFS

minimeteor · November 22, 2007, 7:06am

Hi all,
I am using geoserver1.6RC1 with shapfile datasource.
I am trying to get records with WFS,but the result is none.
The request xml is below:
...
  <wfs:Query typeName="sf:SD_JS_E_DGCENTER_500KV_84">
    <ogc:Filter>
       <ogc:PropertyIsEqualTo>
         <ogc:PropertyName>INTERID</ogc:PropertyName>
        <ogc:Literal>0002103620010001000429</ogc:Literal>
       </ogc:PropertyIsEqualTo>
   </ogc:Filter>
  </wfs:Query>
...
And the response xml is below:
*********************************************
<wfs:FeatureCollection numberOfFeatures="0"
timeStamp="2007-11-22T14:58:24.312+08:00"
xsi:schemaLocation="http://www.openplans.org/spearfish
http://172.16.124.174:8080/geoserverRC/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&typeName=sf:SD_JS_E_DGCENTER_500KV_84

http://172.16.124.174:8080/geoserverRC/schemas/wfs/1.1.0/wfs.xsd">
<gml:featureMembers/>
</wfs:FeatureCollection>
*********************************************

First I can sure that there is one record with the condition.
Second I have tried that query with SDE as the datasource,and the result is
not none.
The response xml is below:
*********************************************

It is so strange.
Thanks in advance of any tips.

Hum, this looks like being either a property name typo or a type mismatch. Can you report the result of calling DescribeFeatureType on the shapefile?
Should look something like:
http://localhost:8080/geoserver/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&typeName=sf:SD_JS_E_DGCENTER_500KV_84

And then do the same on the ArcSDE source.

Cheers

Hum, this looks like being either a property name typo or a type

Should look something like:
http://localhost:8080/geoserver/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&typeName=sf:SD_JS_E_DGCENTER_500KV_84

And then do the same on the ArcSDE source.

Are we sure that shapefile is using the came conversion tactics as
arcsde. The literal in this case starts with zero, i have a feeling
that the shapefile datastore is converting to an integer and those
leading zeros's are being stripped off.

ArcSDE uses the filter encoding stuff that saul did up which actually
checks the type and does the conversion properly.

Could be wrong, just a hunch though.
