Changing schemaLocation in WSDL

Posted on 2016-10-10

I have a WCF Service which I need to host on an old IIS 6 server. The server has a name Server1 but also has an alias used for the website. Apparently the server and the website resolve to different IP addresses.

So WCF Service path is

https://alias.sys.domain.com/ProjectName/MyService.svc?wsdl

Open in new window


But when I look at xml generates, the schemaLocation shows up as:

    <wsdl:types>
      <xsd:schema targetNamespace="http://tempuri.org/Imports">
         <xsd:import schemaLocation="https://server1.subdomain.domain.com/ProjectName/MyService.svc?xsd=xsd0" namespace="http://tempuri.org/" /> 
         <xsd:import schemaLocation="https://server1.subdomain.domain.com/ProjectName/MyService.svc?xsd=xsd2" namespace="http://schemas.datacontract.org/2004/07/ProjectName" /> 
         <xsd:import schemaLocation="https://server1.subdomain.domain.com/ProjectName/MyService.svc?xsd=xsd1" namespace="http://schemas.microsoft.com/2003/10/Serialization/" /> 
       </xsd:schema>
    </wsdl:types>

Open in new window


If I try accessing the schema specified in the xml

https://server1.subdomain.domain.com/ProjectName/MyService.svc?xsd=xsd0

Open in new window




I get "Page cannot be displayed" error, and if I use Network tab in Chrome debug tools, it shows the call has been aborted. But if I try accessing the schema at

https://alias.sys.domain.com/ProjectName/MyService.svc?xsd=xsd0

Open in new window



Then I can get to it without a problem but, unfortunately this is not the one used by the service.

To change that I added httpsGetURL in my config file:

<serviceMetadata httpGetEnabled="true" httpsGetUrl="https://alias.sys.domain.com/ProjectName/MyService.svc"  />

Open in new window


that caused error: "A registration already exists for URI"

which I was able to get rid of by adding "/mex" after ".svc". The strange thing is that I do not have mex endpoint since I cannot use it due to disabled anonymous authentication.

But adding "/mex" caused another error "The message with To 'https://alias.sys.domain.com/ProjectName/MyService.svc/mex?wsdl'
cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher.
Check that the sender and receiver's EndpointAddresses agree."

So then I added address to my endpoint, changing it from

<endpoint address="" binding="webHttpBinding" bindingConfiguration="webBinding" contract="Projectname.IMyService"/>

Open in new window


to

<endpoint address="web1" binding="webHttpBinding" bindingConfiguration="webBinding" contract="Projectname.IMyService"/>

Open in new window


and tried using

https://alias.sys.domain.com/ProjectName/MyService.svc/web1

Open in new window


that changed my error to

The message with Action '' cannot be processed at the receiver, due to a ContractFilter 
mismatch at the EndpointDispatcher. This may be because of either a contract mismatch 
(mismatched Actions between sender and receiver) or a binding/security mismatch between 
the sender and the receiver. Check that sender and receiver have the same contract and 
the same binding (including security requirements, e.g. Message, Transport, None)

Open in new window



Can anyone help?

Hi YZlat,

The space name isn't that important within the WSDL.
Just Install SoapUI (free soap test suit) and create there a Project for your WSDL.

Then you can see in detail what the WSDL is exactly doing

The schemaLocation is determined by your endpoint configuration. But as you're using WebHttpBinding in your config, you're working with a RESTful web service. In this case the WSDL has no meaning, cause it is only for SOAP web services.

@theo kouwenhoven, the problem is not that it is important or unimportant, I was trying to add a service reference to this service from Visual studio and it failed due to invalid value in schemaLocation.

I tried calling it from SOAP UI, created a new project but it failed loading with error:

Error loading 'https://alias.sys.domain.com/ProjectName/MyService.svc?wsdl' org.apache.xmlbeans.XmlException: does not close tag

@ste5an, should I use basicHttpBinding instead?

When it is a RESTful service, then you don't use a WSDL and you don't use the Add service reference menu in VS. You simply use HttpClient or WebClient to send post or get requests to it.

But just to be sure, what your problem is:

You said WCF service, do you mean a SOAP or a RESTful web service?
Have you checked the compatibility of your WCF services used target framework and IIS6? I'm not sure that IIS6 can handle the new ones.
Why do you think the alias is a problem?
How have you configured the alias? And how the web service?

SOAP.


The server is an old Windows 2003 server, the server and web site have different IP addresses. I did not setup the server and all I know is that the service url is:

https://alias.sys.domain.com/ProjectName/MyService.svc

and

somehow https://servername.subdomain.domain.com/ProjectName/MyService.svc somehow get into the xml produced by wsdl

Then the problem is the setup. Your service must run separated from your web site. I guess they share currently the same root.

Solved the issue by changing

    <services>
      <service behaviorConfiguration="basicBehavior" name="ProjectName.MyService">
         <endpoint address="" binding="webHttpBinding" bindingConfiguration="webBinding" contract="Projectname.IMyService"/>
    
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="basicBehavior">
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
      
        </behavior>
      </serviceBehaviors>
    </behaviors>

Open in new window


to

    <services>
