вызвать процесс bpel в android

У меня есть один процесс BPEL. И я хочу назвать это в android. Но я не могу понять URL-адрес wsdl, пространство имен и имя метода. Потому что я знаю, что из-за этого возникает ошибка. Я отправляю файл wsdl и файл xsd.

Мой файл wsdl процесса BPEL:

    <definitions name="HelloWorld" targetNamespace="http://xmlns.oracle.com/HelloWorld" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://xmlns.oracle.com/HelloWorld" xmlns:plnk="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:client="http://xmlns.oracle.com/HelloWorld">
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://xmlns.oracle.com/HelloWorld" schemaLocation="HelloWorld.xsd"/>
        </schema>
    </types>
    <message name="HelloWorldRequestMessage">
        <part name="payload" element="tns:HelloWorldProcessRequest"/>
    </message>
    <message name="HelloWorldResponseMessage">

    </message>
    <portType name="HelloWorld">
        <operation name="process">
            <input message="tns:HelloWorldRequestMessage"/>
            <output message="tns:HelloWorldResponseMessage"/>
        </operation>
    </portType>
    <binding name="HelloWorldBinding" type="tns:HelloWorld">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
        <operation name="process">
            <soap:operation style="document" soapAction="process"/>
            <input>
                <soap:body use="literal"/>
            </input>
            <output>
                <soap:body use="literal"/>
            </output>
        </operation>
    </binding>
    <service name="HelloWorld">
        <port name="HelloWorldPort" binding="tns:HelloWorldBinding">
            <soap:address location="http://www.sample.com/orabpel/default/HelloWorld/1.0"/>
        </port>
    </service>
  <plnk:partnerLinkType name="HelloWorld">
    <plnk:role name="HelloWorldProvider">
      <plnk:portType name="tns:HelloWorld"/>
    </plnk:role>
  </plnk:partnerLinkType>
</definitions>

Мой xsd-файл:

    <schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://xmlns.oracle.com/HelloWorld" xmlns="http://www.w3.org/2001/XMLSchema">
    <element name="HelloWorldProcessRequest">
        <complexType>
            <sequence>
                <element name="input" type="string"/>
            </sequence>
        </complexType>
    </element>
    <element name="HelloWorldProcessResponse">
        <complexType>
            <sequence>
                <element name="result" type="string"/>
            </sequence>
        </complexType>
    </element>
</schema>

Мой код Android:

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        PropertyInfo weightProp =new PropertyInfo();
        weightProp.setName("input");
        weightProp.setValue("sample");
        weightProp.setType(string.class);
        request.addProperty(weightProp);



        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.dotNet = false;
        envelope.bodyOut = request;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try 
        {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            SoapObject obj1 = (SoapObject)envelope.bodyIn;
            Log.i("myApp", response.toString());

        } 
        catch (Exception e) 
        {
            e.printStackTrace();
            Log.d("Exception Generated", ""+e.getMessage());
        }

    }

}

Я получил следующую ошибку:
