how to pass parameter to a webservice using ksoap2?
- by user255681
hi there,
i'm using eclipse to develop over android, i'm trying to connect to a .net webservice...
when i'm calling a webmethod with no parameters it works fine... but when i come to pass a parameter to the webmethod things turn upside down... the parameter is passed as null (while debugging the webservice i discovered that) and i get a null from the webmethod in the client side code... i've been searching for a solution for a day now and all that i can interpreter is that people keep talking about encoding styles and such stuff.... i've tried it all but in vain. i'm using ksoap2 version 2.3 with the following code
package com.examples.hello;
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 android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloActivity extends Activity {
/** Called when the activity is first created. */
private static final String SOAP_ACTION = "http://Innovation/HRService/stringBs";
private static final String METHOD_NAME = "stringBs";
private static final String NAMESPACE = "http://Innovation/HRService/";
private static final String URL = "http://196.205.5.170/mdl/hrservice.asmx";
TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.text1);
call();
}
public void call()
{
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//PropertyInfo PI = new PropertyInfo();
//request.addProperty("a", "myprop");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet=true;
envelope.encodingStyle = SoapSerializationEnvelope.XSD;
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
Object result = (Object)envelope.getResponse();
String results = result.toString();
tv.setText( ""+results);
} catch (Exception e) {
tv.setText(e.getMessage());
}
}
}
