> Using the old client code generated by wsdl2java to call a webservice which has been
extended to support a new operation leads to an exception at runtime:
> javax.xml.ws.WebServiceException: org.apache.cxf.service.factory.ServiceConstructionException:
No method was found for the WSDL operation {http://order.rbp.tmobile.at/services/rbpModifyContract/}rbpNewOperationWithExistingDatatypes.

> I had a look into ReflectionServiceFactoryBean.java (specifically initializeWSDLOperations())
where the exception is thrown

> Seems like the model build from the new wsdl is compared to the old wsdl2java-generated
interface file. If there are any operation not found in the java interface an exception is
thrown. 
> To support backward compatibility and loose coupling between web service providers and
clients, it would be better to ignore methods not mentioned in the java interface file instead,
as they can not be called via the interface anyway.
