We did as suggested, but the error remains the same.
Upon closer inspection, we are confused by the way wsdl2java has
interpreted the WSDL to generate the Java code.
Looking at the WSDL, we expect the operation's response to contain the
elements "submitRawBidSetResponse/outputDataType", shown below with
full
namespace for clarity:
<{http://www.caiso.com/soa/2007-08-16/
submitRawBidSet.wsdl}submitRawBidS
etResponse>
<{http://www.caiso.com/soa/2006-06-13/
SubmitStandardOutput.xsd}outputDat
aType>
</>
</>
Or maybe only the inner element "outputDataType":
<{http://www.caiso.com/soa/2006-06-13/
SubmitStandardOutput.xsd}outputDat
aType>
</>
However, the generated Java code has this signature,
which uses the namespace from one of the above elements and the local
part of the other:
@WebResult(name = "outputDataType"
, targetNamespace =
"http://www.caiso.com/soa/2007-08-16/submitRawBidSet.wsdl";
, partName = "outputDataType")
As a result of this mismatch, the response from the service cannot be
parsed.
Is the signature of the generated Java code correct?
How can we get around this?

If everyone followed the standards, their wouldn't be a
problem...... That's what standards are for. :-(
I'm really not sure why the below isn't working. That looks
completely correct. The only place we call "new RPCInInterceptor()"
in the code is:
sb.getInInterceptors().add(new RPCInInterceptor());
Thus, removing it from the binding like you are doing should work
fine. Very strange. You might need to debug into that one. :-(
Another option might be to use a locally modified WSDL. Change:
<wsdl:part name="returnData"
type="typeOut:outputDataType">
to
<wsdl:part name="outputDataType"
type="typeOut:outputDataType">
An XSLT might be able to automate that.

We set out to replace the standard RPCInInterceptor by our own
modified
copy, which would accept the Axis messages.
We have used the code pattern below, which has proved effective in
replacing other interceptors:
// Replace RPCInInterceptor to ensure compatibility with Axis
i = 0;
for (Interceptor interceptor: binding.getInInterceptors())
{
if (interceptor instanceof RPCInInterceptor)
{
binding.getInInterceptors().remove(i);
System.out.println("RPCInInterceptor removed from
binding.");
}
}
binding.getInInterceptors().add(new MSRPCInInterceptor());
My log shows the following interceptor flow:
Current flow:
receive [LoggingInInterceptor, MSXMLStreamInInterceptor]
post-stream [StaxInInterceptor]
read [ReadHeadersInterceptor, SoapActionInInterceptor]
pre-protocol [MustUnderstandInterceptor, SOAPHandlerInterceptor,
LogicalHandlerInInterceptor]
post-protocol [CheckFaultInterceptor]
unmarshal [URIMappingInterceptor, RPCInInterceptor,
SoapHeaderInterceptor, MSRPCInInterceptor]
post-logical [WrapperClassInInterceptor]
pre-invoke [SwAInInterceptor, HolderInInterceptor]
Note that our interceptor (MSRPCInInterceptor) has been added, but
the
original interceptor (RPCInInterceptor) is still there.
We also get this output, which indicates that RPCInInterceptor should
have been removed (why twice?):
RPCInInterceptor removed from binding.
RPCInInterceptor removed from binding.
We also find this in the log, indicating that the interceptor is
attached to and should be removed from the binding object (and not
other
objects):
Interceptors contributed by binding:

What are we missing? Is there a built-in reason why RPCInInterceptor
cannot be removed from the chain?

The soap message is wrong for an rpc/lit response.
The <ns2:outputDataType> element should be:
<returnData>
Per RPC/Lit rules, the part accessors come from the part names in the
message/parts of the wsdl. They are also supposed to be unqualified
per wsi-bp rules (although some older toolkits do qualify them so our
RPCInInterceptor will allow that, but the out interceptor will not
qualify them).

We have implemented a CXF client from a counterparty-supplied WSDL.
As we call one operation, we get back a response containing valid
business messages.
However, the RPCInInterceptor throws an exception because it "could
not
find matching RPC/Literal part".
We have checked the response, and it contains the element
"outputDataType", which is mentioned in the exception.
In the response, this element's namespace is declared as
"http://www.company.com/soa/SubmitStandardOutput.xsd";.
When we look in the WSDL, I can see that the element outputDataType
is
declared in the operation's return type, with the same namespace.
We do not understand why CXF "could not find matching RPC/Literal
part".
We understand that CXF does not support RPC/Encoded.
However, we have checked that the WSDL conforms to the RPC/Literal
restrictions:
* Each message contains zero or more parts.
* Each part points to a schema type definition that describes the
content of that part.
* In the SOAP binding, the style is "RPC" and the use is
"literal".
What are we missing?
