Hi,
The service requires a login and password, and normally these values are filled
out. But I have removed the username and password from the example for security
reasons. :) It should however still be possible to get the getcapabilities
parsed correctly without username and password.
For example, this WMS service url is working without issues (and without
username and password provided)
https://services.kortforsyningen.dk/service?servicename=fot2007&client=undefined&request=GetCapabilities&service=WMS&version=1.1.1
The only difference I have found in the two WMS getcapability xml's is the
xlink namespace:
In the failing WMS (servicename=topo_geo) the online resource is
<OnlineResource xmlns:xlink="https://www.w3.org/1999/xlink";
xlink:href="https://services.kortforsyningen.dk/topo_geo?&version=1.1.1&service=WMS&request=GetLegendGraphic&layer=Territorialomraade&format=image/png&STYLE=default";
xlink:type="simple"/>
While in the WMS that is working (servicename=fot2007) the online resource is
<OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"; xlink:type="simple"
xlink:href="https://services.kortforsyningen.dk/fot2007?&version=1.1.1&service=WMS&request=GetLegendGraphic&layer=HOEJ_BEBYGGELSE&format=image/png&STYLE=default"/>
The difference is https vs http for the xlink namespace. Could this be related
to the error, and if so, is it an error in geoserver parsing or in the WMS
service itself?

Emne: VS: NPE when creating cascading WMS service
Hi,
That server is as least reporting nonsense as OnlineResource:
<OnlineResource
xlink:href="https://services.kortforsyningen.dk/topo_geo?ignoreillegallayers=TRUE&transparent=TRUE&&";
xlink:type="simple"/>

Aihe: [Geoserver-users] NPE when creating cascading WMS service
Hi,
I'm running geoserver 1.12.1 on windows 7, but have experienced the same issue
on geoserver 1.11.2 on Ubuntu as well.
I have searched the web for solutions to this issue and have not been able to
find any solution, so now I send this mail to the mailinglist.
I want to cascade a remote WMS service on my geoserver, So I add a new
WMS-store (from other data sources), and enter the following values
Workspace: kort (not important, just select an empty workspace)
WMS source name: kort
Capabilities URL:
https://services.kortforsyningen.dk/service?servicename=topo_geo&client=undefined&request=GetCapabilities&service=WMS&version=1.1.1
I leave the rest of the settings for default values, and click save.
Instead of getting an list of layers that can be published, I get an exception:
org.apache.wicket.WicketRuntimeException: Exception 'null' occurred during
validation

I have tried to use the WMS service directly from openlayers, and it works
perfectly, it is just when fetching capabilities from GeoServer that it fails.
