The problem occurs if the service provider is running on a JBI component based on CDK 4, and the service consumer is deployed on a JBI component based on CDK 5.

If we add a NPE check in EasyWSDL Complex extension, the returned WSDL is not correct because the complex WSDLs managed by CDK 4 or CDK 5 use the tag 

{http://petals.ow2.org/wsdlExtensions}importedDocuments/{http://petals.ow2.org/wsdlExtensions}document
with attribute name to store imported resources by the WSDL. And the CDK 5 updates import locations with an XPath expression as 
xpath://description/importedDocuments/document/ServiceFaults.xsd
, and, on tag document, uses attributes location and originalLocation whereas the CDK 4 does not update them and uses attribute name.

This problem won't fix because:

  • the fix is located into the CDK 4 about managing WSDL
  • a component based on the fixed CDK will be not compliant with component based on an older CDK 4

As it is not possible to fix the problem to be compliant CDK 4 (all versions) and CDK 5, it has been decided on:

  • to force to move the service provider on a component based on CDK 5
  • to reference this problem into the BC SOAP documentation

A solution could be to inject imported ressources into the initial WSDL:

<wsdl:definitions targetNamespace="myWsdlNamespace" xmlns:pivot="http://myPivot/1.0" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:svc-api="http://mySvcApi/1.0">
  <wsdl:types>
    <xsd:schema targetNamespace="http://mySvcApi/1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <xsd:import namespace="http://myPivot/1.0" schemaLocation="datamodel_pivot.xsd"/>
      <xsd:element name="myRequest" type="svc-api:myRequestType"/>
    </xsd:schema>
  </wsdl:types>
</wsdl:definitions>

can be rewritten:

<wsdl:definitions targetNamespace="myWsdlNamespace" xmlns:pivot="http://myPivot/1.0" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:svc-api="http://mySvcApi/1.0">
  <wsdl:types>
    <xsd:schema targetNamespace="http://myPivot/1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      ...
    </xsd:schema>
    <xsd:schema targetNamespace="http://mySvcApi/1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

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

Add patch to apply on CDK 4 to have internal WSDL compliant with CDK 5

Can we mark this as wont fix because we don't work with CDK4 anymore? or not?

I don't know what to do. This problem is the symptom of an incompatibility between components based on different CDK versions that are not compliant.

Since the introduction of the distribution "Petals Enterprise", all delivered components are based on the same CDK, so this problem can't occur any more. But is it sufficient ? We wrote any warning on the obligation to use components from the same distribution.
