Hi All
I'm trying to validate my INSPIRE download service (WFS) configured on
GeoServer. One of the first test that validator reports as failed is:
WFS 2.0 Conformance Test Suite -->
org.opengis.cite.iso19142.SuitePreconditions --> dataAreAvailable, which
returns an error saying:
- OGC TEAM Engine reported a failed test: Prerequisite not satisfied:
No valid data available from WFS.
I was a bit intrigued by this error so I tried to catch requests sent from
INSPIRE validator to GeoServer through the monitor plugin to determine what
raises this error. That is when an error caught my eye.
One of the first GET requests from validator is:
https://myserver.com/geoserver/am1/wfs?service=WFS&version=2.0.0&request=GetFeature&count=25&typenames=ns83:AM.RiverBasinDistrict&namespaces=xmlns(xml,http://www.w3.org/XML/1998/namespace),xmlns(ns83,http://inspire.ec.europa.eu/schemas/am/4.0),xmlns(wfs,http://www.opengis.net/wfs/2.0)
Which fails with response:
<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:ows="
http://www.opengis.net/ows/1.1"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"; version="2.0.0"
xsi:schemaLocation="http://www.opengis.net/ows/1.1
https://myserver.com/geoserver/schemas/ows/1.1.0/owsAll.xsd";>
<ows:Exception exceptionCode="InvalidParameterValue" locator="namespace">
<ows:ExceptionText>Unknown namespace []</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
On the other hand if I change namespace*s *parameter into namespace (notice
the missing s) in GET request, the request yields an expected response.
Searching the web I found that prior to WFS 2.0.0 version, the expected
parameter was indeed namespace, and was changed to namespace*s *for
versions 2.0.0+.
So GET request that is currently OK by geoserver (v2.20) is:
https://myserver.com/geoserver/am1/wfs?service=WFS&version=2.0.0&request=GetFeature&count=25&typenames=ns83:AM.RiverBasinDistrict&namespace=xmlns(xml,http://www.w3.org/XML/1998/namespace),xmlns(ns83,http://inspire.ec.europa.eu/schemas/am/4.0),xmlns(wfs,http://www.opengis.net/wfs/2.0)
Has anyone experienced the same issue, and could this be a potential bug,
or is this a server configuration issue?
I'am not entirely sure that this is the exact reason for the failed
validation test, but it is certainly unexpected behavior.
Thank you very much for your answers in advance!
Sincerely,
Luka
