Referencing external schemas in a WSDL

Hello,
I am getting the following error when trying to parse a WSDL and generate the relevant Apex classes in SalesForce:
 
"Error: Failed to parse wsdl: Found schema import from location https://*.xsd. External schema import not supported."
 
I believe that the following (edited) section of the WSDL referring to an external schema is what's causing the problem:
 
...

<wsdl:types>

<xs:schema>

<xs:import namespace="" schemaLocation="https://*.xsd"/>

</xs:schema>

<xs:schema>

<xs:import namespace="" schemaLocation="https://*.xsd"/>

</xs:schema>

</wsdl:types>

...

Can anyone confirm that this is in fact not allowed by Salesforce and if there is any remedy other than embedding the schema in the WSDL?

 
Thanks,
agab-

Hi,

 

I had to deal with an WSDL with external schemas which they also import other schemas. It was a mess at first but the solution was easier than I thought.

 

1. Open the WSDL with a text editor
2. Inside <wsdl:types> (below the last <schema>) paste each referenced .xsd file content. Paste only <schema></schema>
3. Once all schemas are in the WSDL then comment all <xsd:import> using <!-- -->. They are no longer needed.
4. Save and you are ready to go.

 

Some of my classes returned compiling errors because of Exception classes that must extend the Salesforce Exception class. So copy the generated class, correct it into a text editor and then created manually as after clicking "Done", changes are not reprocessed.

Sebastian

Right, xsd:import and wsdl:import are not supported (as the error message indicates). the only solution it to re-work the wsdl to have all the imported schemas in the wsdl document directly.

Ok, thanks for confirming.

Hello,

 

I'm having this same problem and I was trying to follow your instructions to solve this, but I gotta confess I'm not being successful AT ALL!

 

So can I ask for you to please add some code sample to your post? It would be incredibely helpful and greatly appreciated.

 

Thank you in advance.

Hi, try to paste here a short version of your wsdl and one of the referenced .xsd files.

 

I'll see if I can help

Hi, thanks for the fast reply. 

 

I think (!!) I almost got it, but nevertheless, won't hurt to use some expert help.

 

Here is part of my wsdl:

<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:tns="http://www.softlimits.com/Netdocs" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" name="CNDEntityService" targetNamespace="http://www.softlimits.com/Netdocs">
<wsp:Policy wsu:Id="WSHttpBinding_ICNDEntityService_policy">...</wsp:Policy>
<wsp:Policy wsu:Id="BasicHttpBinding_ICNDEntityService_policy">...</wsp:Policy>
<wsdl:types>
<xsd:schema targetNamespace="http://www.softlimits.com/Netdocs/Imports">
<xsd:import schemaLocation="https://e2e.gs1pt.org/Gs1SyncPTe2e/CNDEntityService.svc?xsd=xsd0" namespace="http://www.softlimits.com/Netdocs"/>

...
</xsd:schema>
</wsdl:types>

...

 And here is the .xsd: https://e2e.gs1pt.org/Gs1SyncPTe2e/CNDEntityService.svc?xsd=xsd0

 

Do I have to replace the <xsd:import> for the whole xs:schema? That's it? 

 

Thanks again.

 

EF
Seb OrtizSeb Ortiz

No, try by commenting the xsd:import and paste the whole xsd file content below the last <xsd:schema>

If it does not make it, try replacing the xsd:import with the referenced file content.

 

See below my idea

Let me know how it goes

 

Regards

Ok, so I did this:

<wsdl:types>
<xsd:schema targetNamespace="http://www.softlimits.com/Netdocs/Imports">

</xsd:schema>

</xs:schema>
</wsdl:types>

And I got another error:

Error: Failed to parse wsdl: Found more than one wsdl:binding. WSDL with multiple binding not supported
 
:(
 
Thanks for the help.

Oh, ok. For that, just browse your wsdl for the bindings definitions and comment the one that looks like soapbinding12 or similar, and keep the other one. Save and try again. Regards, Sebastian

Hi Sebastian,

 

It worked! I'm having other problems, but you know... I'll figure it out. 

 

Thank you very so much for you time and help. It was greatly appreciated.
