Android Applicatin consuming ASP.NET Web Service

[erkandoner]

Hi!

I'we written a simple Android java application consuming an ASP.NET web service. But it throws the error message "java.net.ConnectException: localhost/127.0.0.1:8080 - Connection refused" when doing
androidHttpTransport.call(SOAP_ACTION, envelope). Can this error be related to the Network Connections configuration in Eclipse, or any IIS configuration? Here's the code:
(By the way, IIS is runnig, I can reach http://localhost:8080/erkService.asmx and make request, get response wtih internet browser. Get message returns ony a string without taking any input parameter)


package

com.wsImpl;

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.ArrayAdapter;

import​

​

android.widget.AutoCompleteTextView;

public​

​

class ErkActivity extends Activity {

privatestaticfinal String NAMESPACE = "http://artisinerji.com/";
privatestaticfinal String URL = "http://localhost:8080/erkService.asmx?wsdl";​

​

​

privatestaticfinal String SOAP_ACTION = "http://artisinerji.com/GetMessage"; ​

privatestaticfinal String METHOD_NAME = "GetMessage";​

@Override
publicvoid onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);​

setContentView(R.layout.main); ​

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);​

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);​

envelope.setAddAdornments(false);​

​

​

HttpTransportSE androidHttpTransport = ​

​

new HttpTransportSE(URL);

try {​

androidHttpTransport.call(SOAP_ACTION, envelope);​

​

​

SoapObject response = (SoapObject) envelope.​

​

bodyIn;

String result = response.toString();​

} catch (Exception e) {
e.printStackTrace();
}​

}​

}

First, welcome to AF!

Second, I think you'll usually find better responses in the application development forum here: Application Development - Android Forums

To try and answer your question though:

Are you testing in the emulator? I think the IP address to localhost is different in the emulator. It's 10.0.2.2 because ADB uses the traditional localhost IP already at 127.0.0.1 (I think)

Hi,

Thank you very much for your reply. I've changed the URL, now it is so:
http://192.168.5.68:8080/erkService.asmx. Connection is OK now, and I can even work this link in the browser of the emulator and see the web service methods. But I'm receiving another error when I run the code: "
org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://www.w3.org/2001/12/soap-envelope}Envelope (position:START_TAG <{http://schemas.xmlsoap.org/soap/envelope/}soap:Envelope>@1:207 in java.io.InputStreamReader@4052e9d0)"
It cannot parse the wsdl document anyway. I didn't find any useful entry for my situation over internet but go on researching. Have you got any idea?

Hi again,


I solved the issue. I had changed "VER11" to "VER12" in creating the envelope. I rechanged it again to VER11 and now it works, I can get the response from GetMessage method. The last version of the code is below.


Thank you.
