[Geotools-gt2-users] WFS missing output format

[Roar B. <roa...@gm...>]

Hi,

I try to read data from a WFS server, but get the exception:

java.lang.IllegalArgumentException: Client does not support any of the server supported output formats for GET_FEATURE
	at org.geotools.data.wfs.internal.AbstractWFSStrategy.getDefaultOutputFormat(AbstractWFSStrategy.java:403)
	at org.geotools.data.wfs.internal.WFSRequest.<init>(WFSRequest.java:72)
	at org.geotools.data.wfs.internal.GetFeatureRequest.<init>(GetFeatureRequest.java:60)
	at org.geotools.data.wfs.internal.WFSClient.createGetFeatureRequest(WFSClient.java:316)
	at org.geotools.data.wfs.WFSFeatureSource.createGetFeature(WFSFeatureSource.java:231)
	at org.geotools.data.wfs.WFSFeatureSource.getReaderInternal(WFSFeatureSource.java:273)
	at org.geotools.data.store.ContentFeatureSource.getReader(ContentFeatureSource.java:635)
	at org.geotools.data.store.ContentFeatureSource.getReader(ContentFeatureSource.java:579)
	at ReadWFSKommuner.main(ReadWFSKommuner.java:22)



When I look at the capabilities document(1 <https://wfs.geonorge.no/skwms1/wfs.administrative_enheter?&service=WFS&acceptversions=2.0.0&request=GetCapabilities>), I see that there isn't specified any outputFormat for operation GET_FEATURE, but there seems to be a global declaration for all operations:

<ows:Operation name="GetFeature">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:href="https://wfs.geonorge.no/skwms1/wfs.administrative_enheter?"/>
<ows:Post xlink:href="https://wfs.geonorge.no/skwms1/wfs.administrative_enheter?"/>
</ows:HTTP>
</ows:DCP>
</ows:Operation>
....
<ows:Parameter name="outputFormat">
<ows:AllowedValues>
<ows:Value>text/xml; subtype=gml/3.2.1</ows:Value>
<ows:Value>application/gml+xml; version=3.2</ows:Value>
</ows:AllowedValues>
</ows:Parameter>

Has anyone experienced something similar, or can someone tell me if Geotools should have taken this parameter into account?

Best regards,

Roar Brænden
