Re: [Geoserver-users] NPE when creating cascading WMS service

Thu, 07 Dec 2017 03:25:50 -0800 

Hi all,
I did a quick debug, the /NullPointerException/ exception happens when parsing /OnlineResource /elements of styles legends like this one: 

   <Style>
      <Name>default</Name>
      <Title>Bygning, BBR punkt</Title>
      <LegendURL height="21" width="113">
        <Format>image/png</Format>
        <OnlineResource *xmlns:xlink="https://www.w3.org/1999/xlink"*
   
xlink:href="https://services.kortforsyningen.dk/topo_geo?&amp;version=1.1.1&amp;service=WMS&amp;request=GetLegendGraphic&amp;layer=Bygning_BBR_P&amp;format=image/png&amp;STYLE=default";

                        xlink:type="simple"/>
      </LegendURL>
   </Style>


The exception happens because the value of the /xmlns:xlink/ attribute doesn't respect the prefixed 
value defined by WMS 1.1.1 capabilities document DTD [1]:


   <!-- An OnlineResource is typically an HTTP URL. The URL is placed in the
   xlink:href attribute.  The xmlns:xlink attribute is a required XML namespace
   declaration. -->
   <!ELEMENT OnlineResource EMPTY>
   <!ATTLIST OnlineResource
   *xmlns:xlink CDATA #FIXED "http://www.w3.org/1999/xlink"*
              xlink:type CDATA #FIXED "simple"
              xlink:href CDATA #REQUIRED >

It should be *http://www.w3.org/1999/xlink* and not 
*https://www.w3.org/1999/xlink*.

So I see two options:

 * make the remote server be compliant with WMS 1.1.1
 * make GeoServer capable of accepting this non compliant capabilities document

Nuno Oliveira

Hi,


Sorry, my own answer was nonsense. The GetCapabilities look good on the browser but the error 
seems to mean that the XML parser stops to some error when it is resolving the GetLegendGraphics 
URLs. I believe that the difference that you found is related.  The error happens here


Caused by: java.lang.NullPointerException


              at 
org.geotools.data.wms.xml.WMSComplexTypes$_LegendURLType.getValue(WMSComplexTypes.java:4352)



I tried to validate the GetCapabilities XML with an online validator and it did not find errors. 
Let’s hope that real developers will have a look.

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. JIt 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


<OnlineResourcexmlns: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?&amp;version=1.1.1&amp;service=WMS&amp;request=GetLegendGraphic&amp;layer=HOEJ_BEBYGGELSE&amp;format=image/png&amp;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?

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"/>

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 
org.geoserver.web.data.store.WMSStoreNewPage$WMSCapabilitiesURLValidator on component
