Hi All
An update on this issue. I have now managed to get the CXF-BC component to
parse the WSDL by modifying a couple of parts of it. I have not as yet had
time to work out the exact cause of this problem in the SM code. The elements I
had to change were as follows:
<xsd:schema elementFormDefault="qualified">
<xsd:element name="SecretToken" nillable="true"
type="win:SecretHeader"/>
</xsd:schema>
I had to move the namespace from this element and declare it on the root node
of the WSDL. This also required adding the namespace to a couple of nodes -
same for the below two nodes:
<wsdl:message
name="ICorporateOperations_SelectAllFundsAsList_DetailedFaultFault_FaultMessage">
<wsdl:part name="detail" element="q5:DetailedFault"/>
</wsdl:message>
<wsdl:message
name="ICorporateOperations_SelectFunds_DetailedFaultFault_FaultMessage">
<wsdl:part name="detail" element="q5:DetailedFault"/>
</wsdl:message>
I will try to investigate the exact cause of this, but if anyone has time to
look that would be great. I simply found out the information above by
debugging on the method shown in my previous post, I have not as yet worked out
where the namespace is read, and why it does not try the local node to read the
namespace from.
Thanks
Ben

Hi JB
Sorry I didn't attach the deployment log before - I have attached the full log
- changed some of the URL's slightly.
I have tracked things down further and the error actually seems to occur on the
SecretToken element of the WSDL:
<xsd:schema elementFormDefault="qualified">
<xsd:element
xmlns:q3="http://schemas.datacontract.org/2004/07/Winterthur.SoapHeaderFactory";
name="SecretToken" nillable="true" type="q3:SecretHeader"/>
</xsd:schema>
This appears to be the element where the namespace "ns1" with no URI is
inserted into the namespaces element of the WSDL Definition (in
ServiceWsdlBuilder.buildMessage(message, messageContainer, def)).
I don't think I have said this yet, but the reason I believe there might be an
issue in SM is that SoapUI can communicate with this web service without error.
If you need anything else please let me know.
Ben

Hi Ben,
correct, the load of the WSDL is made into the validate() method. It's
here that the component get the target WSDL, parse it and load.
On my side, I have requested the target WSDL and the deployment debug
log, to try to load it (in a debugged unit test) and see why we have an
error in the javax.xml loader.
Could you provide both please ?
Regards
JB
