java - 错误 :org. ksoap2.SoapFault 服务类对象没有实现需要的方法

Question

我在 java 中使用 axis2 创建了用于将两个数字相乘的 web 服务..

wsdl文件是

我正在使用 ksoap2 在 android 中调用网络服务。

Android 客户端代码是:

   import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.ksoap2.SoapFault;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;


public class Addd extends Activity {

    EditText edit1,edit2;
    Button button1;
    TextView text1;


    private String METHOD_NAME = "multiply"; // our webservice method name
    private String NAMESPACE = "http://muliply.example.com"; // Here package name in webservice with reverse order.
    private String SOAP_ACTION = "http://muliply.example.com/multiply"; // NAMESPACE + method name
    private static final String URL = "http://192.168.100.193:9998/Multiplication/services/Mul?wsdl" ;// you must use ipaddress here, don’t use Hostname or localhost


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        edit1  =(EditText) findViewById(R.id.fnumber);
        edit2  =(EditText) findViewById(R.id.snumber);
        button1=(Button) findViewById(R.id.badd);
        text1  =(TextView) findViewById(R.id.result);


        button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                try
                {

                //int a=Integer.parseInt(edit1.getText().toString());
                //int b=Integer.parseInt(edit2.getText().toString());

                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                PropertyInfo num1 = new PropertyInfo();
                num1.setName("a");
                num1.setValue(5);
                request.addProperty(num1);

                PropertyInfo num2 = new PropertyInfo();
                num2.setName("b");
                num2.setValue(9);
                request.addProperty(num2);


                //request.addProperty("a", 10);
                //request.addProperty("b",11);
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            //  envelope.dotNet = true;
                envelope.setOutputSoapObject(request);
                HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
                androidHttpTransport.call(SOAP_ACTION,envelope);
                Object result = envelope.getResponse();
                System.out.println("Result :"+ result.toString());
                text1.setText("Addition : "+result.toString());
                } catch (Exception E) {
                E.printStackTrace();
                ((TextView) findViewById (R.id.result)).setText("ERROR:"   + E.getClass().getName() + ":" + E.getMessage());
                }

            }
        });







    }

}

我收到此错误:Error:org.ksoap2.SoapFault The service class object does not implement the required method in the following form OMElement multiply(OMElement e)

如何解决这个错误？任何答案都会对我有帮助

在你的services.xml文件中添加这个

<operation name="Your method name" >
    <messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
    </operation>
