WSDL Exception

[Antonio Acevedo Bañez]

i cant validate the wsdl of this example https://pythonhosted.org/WSME/gettingstarted.html

SoapUI said me:

        WSDLException (at /wsdl:definitions/wsdl:binding/wsdl:operation[1]/wsdl:operation): faultCode=INVALID_WSDL: Encountered illegal extension element '{http://schemas.xmlsoap.org/wsdl/}operation' in the context of a 'javax.wsdl.BindingOperation'. Extension elements must be in a namespace other than WSDL's 

could someone help me? i want to access my WS with java.
