Hi App-Schema experts,
I'm trying to map a PostGIS table with columns
...
point GEOMETRY NOT NULL,
height INTEGER NOT NULL,
height_uom TEXT NOT NULL
to the following XML structure:
<myns:MyFeature gml:id="...">
<myns:myPoint>
<myns:MyPoint gml:id="..."
srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";>
<gml:pos>10.4721897381 43.2874901353</gml:pos>
<myns:height uom="FT">3</myns:height>
</myns:MyPoint>
</myns:myPoint>
</myns:MyFeature>
That is, the type of myns:MyPoint is an extension of gml:Point with
an additional element. The corresponding part of the XML schema is:
<complexType name="MyPointType">
<complexContent>
<extension base="gml:PointType">
<sequence>
<element name="height" type="gml:MeasureType"/>
</sequence>
</extension>
</complexContent>
</complexType>
I've tried lots of variants of the following mapping:
<AttributeMapping>
<targetAttribute>myns:myPoint</targetAttribute>
<sourceExpression>
<OCQL>point</OCQL>
</sourceExpression>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>myns:myPoint/myns:MyPoint/myns:height</targetAttribute>
<sourceExpression>
<OCQL>height</OCQL>
</sourceExpression>
<ClientProperty>
<name>uom</name>
<value>height_uom</value>
</ClientProperty>
</AttributeMapping>
But I always got the following exception:
java.lang.RuntimeException: Failed to get property: gid
Failed to get property: gid
org.geotools.feature.ComplexAttributeImpl cannot be cast to
com.vividsolutions.jts.geom.Geometry
... [1]
Note that the "gid" attribute is optional and even deprecated!
Nevertheless, I added it via the following mapping rule:
<AttributeMapping>
<targetAttribute>myns:myPoint/myns:MyPoint</targetAttribute>
<ClientProperty>
<name>gid</name>
<value>'DUMMY'</value>
</ClientProperty>
</AttributeMapping>
Then, I got the same error message regarding many other optional(!)
attributes. After providing dummy mappings for them, GeoServer finally
produced an output, but that output didn't contain the geometry data:
<myns:MyFeature gml:id="...">
<myns:myPoint>
<myns:MyPoint axisLabels="DUMMY" gid="DUMMY" gml:id="DUMMY"
srsDimension="DUMMY" srsName="DUMMY" uomLabels="DUMMY">
<myns:height uom="FT">3</myns:height>
</myns:MyPoint>
</myns:myPoint>
</myns:MyFeature>
I also tried to map the geometry to the MyPoint sub element:
<AttributeMapping>
<targetAttribute>myns:myPoint/myns:MyPoint</targetAttribute>
<sourceExpression>
<OCQL>point</OCQL>
</sourceExpression>
...
</AttributeMapping>
Although the "point" column was not NULL, it produced the following
strange exception:
org.geotools.feature.IllegalAttributeException:http://example.com/myns:MyPointType
not nillable:null value:null
... [2]
What am I doing wrong here?
Greets,
Volker
