I am attempting to post the following xml through geoserver to make a WFS insert:

<wfs:Transaction xmlns:wfs="http://www.opengis.net/wfs/2.0" service="WFS" version="2.0.0" xmlns:gml="http://www.opengis.net/gml/3.2" xmlns:my_db="http://localhost:8080/geoserver/schemas/my_db" xsi:schemaLocation="http://www.opengis.net/wfs/2.0 http://schemas.opengis.net/wfs/2.0/wfs.xsd http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/gml.xsd http://localhost:8080/geoserver/schemas/my_db http://localhost:8080/geoserver/wfs/DescribeFeatureType?typename=test_db:avoidance_points" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <wfs:Insert>
    <my_db:avoidance_points>
      <my_db:weight>2</my_db:weight>
    </my_db:avoidance_points>
  </wfs:Insert>
</wfs:Transaction>

The schema at the specified url ([...]/wfs/DescribeFeatureType?[...]) is as follows, and the relevant store is backed by a postgis database.

<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:gml="http://www.opengis.net/gml/3.2" xmlns:test_db="test_db" xmlns:wfs="http://www.opengis.net/wfs/2.0" elementFormDefault="qualified" targetNamespace="test_db">
  <xsd:import namespace="http://www.opengis.net/gml/3.2" schemaLocation="http://192.168.1.19:8080/geoserver/schemas/gml/3.2.1/gml.xsd"/>
  <xsd:complexType name="avoidance_pointsType">
    <xsd:complexContent>
      <xsd:extension base="gml:AbstractFeatureType">
        <xsd:sequence>
          <xsd:element maxOccurs="1" minOccurs="0" name="geom" nillable="true" type="gml:PointPropertyType"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="distance" nillable="true" type="xsd:int"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="weight" nillable="true" type="xsd:int"/>
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
  <xsd:element name="avoidance_points" substitutionGroup="gml:AbstractFeature" type="test_db:avoidance_pointsType"/>
</xsd:schema>

This results in no insertions. I am aware that, as I'm attempting to simplify the problem as much as possible for debugging, I am not specifying all values within the schema (geom, distance), but neither of these are set to 'not null', so I don't expect that this is my underlying issue.

After putting geoserver into verbose logging, the following appears in the log:

My interpretation of this is that somehow, geoserver is failing to load my my_db namespace. How can I fix this?

Your features are in the test_db namespace not the my_db which is why the lookup of the schema fails.

See:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:gml="http://www.opengis.net/gml/3.2"
  xmlns:test_db="test_db" xmlns:wfs="http://www.opengis.net/wfs/2.0"                        elementFormDefault="qualified" targetNamespace="test_db">

  • This worked for me, but I'm not entirely sure why. I would have expected that by manually specifying it in schemaLocations it would have made itself work. At the same time, I'm now having the issue that it's complaining about "Source was null in trying to create a reprojected feature collection", which is strange since I'm not even including any geometries yet. Odd!

  • Your way would be ok iff the describeFeatureType response returned a schema for my_db but it doesn't - at least I think that's the problem
