Problem handling external WSDLs with multiple namespaces
--------------------------------------------------------
Key: ODE-379
URL: https://issues.apache.org/jira/browse/ODE-379
Project: ODE
Issue Type: Bug
Components: Axis2 Integration
Affects Versions: 1.2
Reporter: Jon Coogan
I think I've discovered a bug in the way Ode 1.2 handles external WSDLs that
contain multiple namespaces. For example, I have a web service that has the
following format:
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/";
xmlns:plnk="http://docs.oasis-open.org/wsbpel/2.0/plnktype";
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"; xmlns:xyzNamespace="xyz"
name="SampleService" targetNamespace="abc">
<plnk:partnerLinkType name="SamplePartnerLinkType">
<plnk:role name="SampleRole" portType="xyzNamespace:SamplePortType"/>
</plnk:partnerLinkType>
<import location="xyz.wsdl" namespace="xyz"/>
<service name="SampleService">
<port binding="xyzNamespace:SamplePortBinding" name="SamplePort">
<soap:address location="http://xxxxxx/Sample"/>
</port>
</service>
</definitions>
The target namespace of the WSDL is "abc", but the service
binding/operations/faults/etc are actually declared in the "xyz" namespace. As
far as I can tell, this is perfectly legal.
The problem is that I can't get fault handling to work at all with a service
like this. The WSDL defines a fault in the xyz namespace. When I encounter
the fault, I see this in the Ode log:
WARN [SoapExternalService]: Fault response: faultType={abc}SampleFault
What's puzzling about this is that the namespace is wrong. The SampleFault is
declared in the xyz namespace, not the abc namespace. I surmised that Ode
somehow assumes that the faults (and possibly other things) reside in the same
namespace as the top-level WSDL.
I did some snooping and found some code that seems to confirm this. See
parseSoapFault() in:
http://svn.apache.org/repos/asf/ode/tags/APACHE_ODE_1.2/axis2/src/main/java/org/apache/ode/axis2/util/SoapMessageConverter.java.
The last line jumped out at me:
return new QName(_def.getTargetNamespace(), fdef.getName());
Now I am not very familiar with the Ode sources, but it looks the namespace is
being pulled off the top-level definition. In this case, that is incorrect
because the fault actually has a different namespace.
I wonder if there are other areas where the same kinds of assumptions are made.
