> I'm trying to use a simple ClientProxyFactoryBean to connect to a dosgi-exported service. Without specifying the wsdl url, it doesn't work since apparently the method argument names don't match (arg0 vs actual parameter name, as explained in CXF-897), so I added the wsdl url. Now service methods that have a return value seem to work ok, but those with void return type do not.
> Further investigation suggests that the issue might be in ReflectionServiceFactoryBean: initializeWSDLOperation prints out a warning (no method for op) instead of binding the operation, because initializeClassInfo returns false, because initializeParameter called with the return type (near the bottom of initializeClassInfo) returns false, since o.getOutput().getMessagePart/getMessagePartByIndex return null (since there are no parts - the method can throw an exception, for which the output message exists, but there is no actual return type).
> A quick test in the debugger shows that if I manipulate the flow manually (e.g. execute the if caluse in initializeWSDLOperation after initializeClassInfo returns) then the method invocation works ok.
> I am not familiar with the inner workings of WSDL or these classes, so I'm not sure what is the correct place to apply a fix.
