Java Web Services with ksoap2 for android

Question

I am implenting java web services for android project and calling with KSOAP2.
My Code is mention below..

package com.android.service;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MyAndroidService extends Activity {
    private static final String NAMESPACE = "http://project.com/";
    private static final String METHOD_NAME = "sayHello";
    String SOAP_ACTION = "http://project.com/sayHello";
    private static final String URL = 
            "http://localhost:8080/MyProject/wsdl/Hello.wsdl";  
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv=(TextView)findViewById(R.id.text);

        try{
            SoapObject object=new SoapObject(NAMESPACE, METHOD_NAME);
            object.addProperty("name", "dev");
            SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.setOutputSoapObject(object);
            HttpTransportSE httpTransportSE=new HttpTransportSE(URL);
            httpTransportSE.call(SOAP_ACTION, envelope);
            Object result=envelope.getResponse();
            System.out.println("result :"+result.toString());
        }catch (Exception e) {
            System.out.println(e);
        }
    }
}

but we are always getting an extion which is also mention below

It obviously can't find the ksoap2 jar at runtime.

You may check that your jar is exported when building apk: in project Properties > Java Build Path, go to the 'Order and Export' folder and fill the checkbox corresponding to your jar. And rebuild.

So you don't get the previous NoClassDefFoundError error anymore? – sdabet Aug 28 '12 at 12:59
thanks sir but after that we are getting exception just like above can u help me how to resolve it. – user1412354 Aug 29 '12 at 04:26
That looks like a totally different problem now (obviously an error of response parsing). You should consider creating a new question for this. – sdabet Aug 29 '12 at 07:04
