Web Service XML request format from WSDL

I am starting up with web service and I have just faced up a doubt. I have the WSDL file and I want to develop the web service. I have tried out with Axis2 and CXF and I do not know if the problem is conceptual, or technical.

My tutor give me this wsdl file:

<wsdl:types>
    <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://ws.unit4.com">

        <xs:element name="InsertDog">
            <xs:complexType>
                <xs:sequence>
                    <xs:element minOccurs="0" name="param0" nillable="true" type="xs:string"/>
                </xs:sequence>
            </xs:complexType>
        </xs:element>

        <xs:element name="InsertDogResponse">
            <xs:complexType>
                <xs:sequence>
                    <xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/>
                </xs:sequence>
            </xs:complexType>
        </xs:element>

    </xs:schema>
</wsdl:types>

<wsdl:message name="InsertDogRequest">
    <wsdl:part name="parameters" element="ns:InsertDog"/>
</wsdl:message>

<wsdl:message name="InsertDogResponse">
    <wsdl:part name="parameters" element="ns:InsertDogResponse"/>
</wsdl:message>

<wsdl:portType name="InsertDogPortType">
    <wsdl:operation name="InsertDog">
        <wsdl:input message="ns:InsertDogRequest" wsaw:Action="urn:InsertDog"/>
        <wsdl:output message="ns:InsertDogResponse" wsaw:Action="urn:InsertDogResponse"/>
    </wsdl:operation>
</wsdl:portType>

<wsdl:binding name="InsertDogSoap11Binding" type="ns:InsertDogPortType">
    <soap:binding transport="http://ift.tt/LcBaVu" style="document"/>
    <wsdl:operation name="InsertDog">
        <soap:operation soapAction="urn:InsertDog" style="document"/>
        <wsdl:input>
            <soap:body use="literal"/>
        </wsdl:input>
        <wsdl:output>
            <soap:body use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

<wsdl:service name="InsertDogServ">
    <wsdl:port name="InsertDogHttpSoap11Endpoint" binding="ns:InsertDogTransSoap11Binding">
        <soap:address location="x.x.x.x"/>
    </wsdl:port>
</wsdl:service>

And my tutor said me also that this web service has to be able to receive and XML document like:

<soapenv:Envelope xmlns:soapenv="http://ift.tt/sVJIaE" xmlns:q0="http://ws.unit4.com" xmlns:xsd="http://ift.tt/tphNwY" xmlns:xsi="http://ift.tt/ra1lAU">
  <soapenv:Body>
      <NewDog xmlns="http://gfr.com/">
          <name>Kira</name> 
          <owner>John Smith</owner> 
          <contactNumber>123456789</contactNumber>
      </NewDog>
  </soapenv:Body>
</soapenv:Envelope>

But I receive an error like:

...      
<soapenv:Fault>
<faultcode xmlns:ns1="http://ift.tt/1f4HjAN">ns1:Client</faultcode> 
<faultstring>No such operation 'NewDog'</faultstring> 
...

I do not know if I am wrong or not, but, shouldn't be the wsdl schema part like this one below to work out with this XML request?

<xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://ws.unit4.com">

    <xs:element name="NewDog">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="name" nillable="true" type="xs:string"/>
                <xs:element minOccurs="0" name="owner" nillable="true" type="xs:string"/>
                <xs:element minOccurs="0" name="contactNumber" nillable="true" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="InsertDogResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

</xs:schema>

Thank you very much in advance :) and happy weekend!!
