I have read that Geoserver is quite strict with XML validation, and tries to check everything deeply.

Objet : Re: [Geoserver-users] WFS cascade : impossible to publish a layer
Well the layers name is “Centres_et_postes_de_secours:Centres_et_postes_de_secours” so that’s correct. On my machine I get
Caused by: org.geotools.data.DataSourceException: No XSDElementDeclaration found for {https://dservices1.arcgis.com/B0HauZcvLgYIRu8z/arcgis/services/Centres_et_postes_de_secours/WFSServer}Centres_et_postes_de_secours

as the root error. That looks like the request to get the DescribeFeatureType is not working - but https://dservices1.arcgis.com/B0HauZcvLgYIRu8z/arcgis/services/Centres_et_postes_de_secours/WFSServer?service=wfs&request=DescribeFeatureType&typeName=Centres_et_postes_de_secours:Centres_et_postes_de_secours does work for me in the browser.
Turning the logging level up gives:

So it seems as though the XSD file returned is invalid but I’m not sure why
(All the above were with the arcgis strategy)

Hi,
My configuration :
Apache Tomcat/8.5.14 (Debian)
Geoserver 2.14.0
WFS capabilities URL : https://dservices1.arcgis.com/B0HauZcvLgYIRu8z/arcgis/services/Centres_et_postes_de_secours/WFSServer?service=wfs&request=getcapabilities
I try to cascade and publish a WFS layer but I always get the same error, even after playing with the store parameters (WFS versions, protocol strategy, etc…)
Via browser : no problem
Via QGIS (3.6 Noosa) : no problem. And, first saved as a shapefile and then exported in PostgreSQL, I can add it in Geoserver as a PostGIS store and previsualize it.
REM : just befor publishing the layer, the layer name is a bit weird : « Centres_et_postes_de_secours_Centres_et_postes_de_secours », as if the name were doubled with a namespace prefix (the typename to use in a GetFeature with a simple URL in the browser is « Centres_et_postes_de_secours :Centres_et_postes_de_secours » and the XML response is OK with all the features)
I suspect an issue with the layer name containing underscores, maybe…
Any idea ?
