I created the webservice for multiplying two numbers using axis2 in java..
The wsdl file is

I am calling the webservice in android using ksoap2.
Android client side code is:
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());
}
}
});
}
}
I got this error: Error:org.ksoap2.SoapFault The service class object does not implement the required method in the following form OMElement multiply(OMElement e)
How to resolve this error? Any answers will help me
Add this is in your services.xml file
<operation name="Your method name" >
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
