Ksoap android throws http 502 error.

[Charanjeet Singh]

Hi,

I am trying to call soap web service using ksoap and passing credentials in header.

I am getting exception:

Http request failed. Http Status 502

at line no. 129 ie transport.call(SOAP_ACTION, soapEnvelope);

Please find the code below, please help

Code:

package abcd;

import android.content.Intent;

import android.os.AsyncTask;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

public class PolicyNumber extends AppCompatActivity {

    String TAG = "Response";

    SoapPrimitive resultString;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_policy_number);

        addClickListener();

    }

    private void addClickListener() {

        Button button = (Button)findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                Intent i = new Intent(getApplicationContext(),PolicyDetails.class);

                EditText editText = (EditText)findViewById(R.id.editText);

                i.putExtra("PolicyNumber",editText.getText().toString());

                i.putExtra("CustomerName", "Customer");

                AsyncTaskRunner task = new AsyncTaskRunner();

                task.execute();

                }

            }

        );

        }

        @Override

        }

        @Override

            Toast.makeText(getApplicationContext(), "Response" + result, Toast.LENGTH_LONG).show();

        }

    }

    public Object calculate(String userName, String password, String policyNo) {

        final String SOAP_ACTION = "http://schemas.cordys.com/DPLIEAppRpDBWSAppServerPackage/GetPolicyDetail";

        final String METHOD_NAME = "GetPolicyDetail";

        final String NAMESPACE = "http://schemas.cordys.com/DPLIEAppRpDBWSAppServerPackage/";

            PropertyInfo policyNumber = new PropertyInfo();

            policyNumber.setName("policyNo");

            policyNumber.setValue("1234");

            policyNumber.setType(String.class);

            Request.addProperty(policyNumber);

            SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

            //create header

            Element[] header = new Element[1];

            header[0] = new Element().createElement("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd","Security");

            Element usernametoken = new Element().createElement("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", "UsernameToken");

            header[0].addChild(Node.ELEMENT, usernametoken);

            Element username = new Element().createElement("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", "Username");

            username.addChild(Node.TEXT,"user1");

            usernametoken.addChild(Node.ELEMENT, username);

            Element pass = new Element().createElement("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd","Password");

            pass.addChild(Node.TEXT,"pass1");

            usernametoken.addChild(Node.ELEMENT,pass);

            soapEnvelope.headerOut = header;

            soapEnvelope.dotNet = false; 

            soapEnvelope.bodyOut = Request;

            soapEnvelope.implicitTypes = true;

            soapEnvelope.setAddAdornments(false);

            soapEnvelope.setOutputSoapObject(Request);

            System.out.println(soapEnvelope.toString());

            HttpTransportSE transport = new HttpTransportSE(URL,60000);

            transport.call(SOAP_ACTION, soapEnvelope);

            response = soapEnvelope.getResponse();

        } catch (Exception ex) {

            Log.e(TAG, "Error: " + ex.getMessage());

        }

        return response;

    }

}

Sample Request should look like this:

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">

    <Header>

        <Security xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

            <UsernameToken>

                <Username>[string]</Username>

                <Password>[string]</Password>

            </UsernameToken>

        </Security>

    </Header>

    <Body>

        <GetPolicyDetail xmlns="http://schemas.cordys.com/DPLIEAppRpDBWSAppServerPackage">

            <policyNo>[string]</policyNo>

        </GetPolicyDetail>

    </Body>

</Envelope>

Please help.
