complex types

When I try to run

 

Definition def = WSIFUtils.readWSDL(null,wsdl);

 

......

 

WSIFServiceFactory factory = WSIFServiceFactory.newInstance();

                                    

WSIFService service = factory.getService(def, serviceWsdl,
portTypeWsdl);

 

If the wsl file contains complex types, I get

 

java.lang.ClassCastException

any idea ?? 

thanks
