I'm trying to access a Java Web Service from Android client, but it is showing me an error:

"java.lang.classcastexception org.ksoap2.soapfault cannot be cast to org.ksoap2.serialization.soapobject"

Can you help me?

Here is my client web service code:

import java.lang.reflect.Method;

import android.app.Activity; 
import android.os.Bundle; 
import android.content.Context;
import android.content.Intent; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View;
import android.view.Window;
import android.widget.EditText;

import android.widget.TextView;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.ksoap2.transport.HttpTransportSE; 

public class Loginuser extends Activity{


public static final int MENU1 = Menu.FIRST; 
public static final int MENU2 = Menu.FIRST + 1; 
public static final int MENU3 = Menu.FIRST + 2; 
public static Context group;

    private static final String SOAP_ACTION = "";
    private static final String METHOD_NAME = "logar";
    private static final String NAMESPACE = "http://wsproj.mycompany.com/";
    private static final String URL = "http://localhost:8084/wsproj/HelloWorld";


    EditText ura,pw; 

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.loginuser);

    }


    public void logar(View X) { 
    CarregaTelaBolarq();
    }

public void CarregaTelaBolarq(){

    ura=(EditText)findViewById(R.id.editText2);
    String raforn = ura.getText().toString();

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);


    request.addProperty("raforn",ura.getText().toString());

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);


try{

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapObject sp = (SoapObject)envelope.bodyIn;

    String result=sp.toString();

    if(result.equals("1"))

            {

               TextView tv; 
               tv=(TextView) findViewById(R.id.editText1);
               tv.setText("foi: ");
            }
            else
            {
                TextView tv; 
                tv=(TextView) findViewById(R.id.editText1);
                tv.setText("Msg from service: ");
            }       

        }
        catch(Exception e)
        {

            TextView tv=(TextView) findViewById(R.id.editText1);
            tv.setText("ERROR: " + e.toString());
        }

}




public boolean onCreateOptionsMenu(Menu options) { 
options.add(0, MENU1, 0, "Página Principal");
options.add(0, MENU2, 0, "Manual");
options.add(0, MENU3, 0, "Sobre");

return super.onCreateOptionsMenu(options);   }


public boolean onOptionsItemSelected(MenuItem item) {   
    switch (item.getItemId()) { 
    case MENU1: 
        Intent mudarHome= new Intent(this, MainActivity.class); 
        startActivity(mudarHome);  
        return true;

    case MENU2: 
        Intent mudarManual = new Intent(this, Manual.class); 
        startActivity(mudarManual); 
        return true;

    case MENU3: 
        Intent mudarSobre = new Intent(this, Sobre.class); 
        startActivity(mudarSobre);  
        return true;

        }   
        return false;   
        }
    }

That's means there is no service found by those parameters try this code to find the error message :

SoapFault error = (SoapFault)envelope.bodyIn;
System.out.println("Error message : "+error.toString());

in my opinion you must fill the SOAP_ACTION parameter by the class that include the service with the package name :

private static final String SOAP_ACTION = "http://com.mycompany.wsproj/HelloWorld";

and end the URL of the web service by .wsdl or ?wsdl ( try them both xD )

private static final String URL = "http://localhost:8084/wsproj/HelloWorld?wsdl";

one last important thing is (when you are using android API ) change the localhost by the IP :

private static final String URL = "http://10.0.2.2:8084/wsproj/HelloWorld?wsdl";

Hope that helps you !! ... good luck !
