Send date to the server using Ksoap2

Question

I'm trying to send request to the server, and one of the argument there should to have type date. How to set type date? Because right now my request has type string.

Request which I'm sending to the server:

    <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:d="http://www.w3.org/2001/XMLSchema"
    xmlns:c="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
            <v:Header /><v:Body><n0:getOutlets id="o0" c:root="1" xmlns:n0="http://www.kltro.com">
            <userId i:type="d:string">a24f0c23-5f36-11e4-b332-984be174a0cc</userId>
            <date i:type="d:string">2016-08-25</date>
</n0:getOutlets>
</v:Body>
</v:Envelope>

Activity for the sending request:

public class MainActivity extends AppCompatActivity {

    private static final String NAMESPACE = "http://www.kltro.com";
    private static final String METHODNAME = "getOutlets";
    private static final String WSDL = "http://mapx.kashkan.org:5445/tro/ws/kltro";
    private static final String SOAP_ACTION = NAMESPACE + "#kltro:" + METHODNAME;
    private static String TAG = "soap";

    public static String callWebservice() {
        String responseDump = "";
        String requestDump="";

        try {
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

            SoapObject request = new SoapObject(NAMESPACE, METHODNAME);
            request.addProperty("userId", "a24f0c23-5f36-11e4-b332-984be174a0cc");
            request.addProperty("date", "2016-08-25");

            envelope.bodyOut = request;
            HttpTransportSE transport = new HttpTransportSE(WSDL);
            transport.debug = true;
            try {
                transport.call(SOAP_ACTION, envelope);
                requestDump = transport.requestDump;
                responseDump = transport.responseDump;

                Log.e(TAG, requestDump +"requestDump");
                Log.e(TAG, responseDump+"responseDump");
            } catch (IOException e) {
                e.printStackTrace();

                Log.e(TAG, requestDump +"requestDump");
                Log.e(TAG, responseDump+"responseDump");
            }

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

            Log.e(TAG, requestDump+"responseDump");
            Log.e(TAG, responseDump+"responseDump");
        }

        Log.e("requestDump", requestDump);
        Log.e(TAG, responseDump+"responseDump");
        return responseDump;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        callWebservice();
    }
}

Sending a date through ksoap2-android library is a bit more complicated. ksoap2-android library does not know to serialize(or marshal) the type date. So you need to give a custom Marshal class.

But luckily ksoap2-android library already has a MarshalDate class. See its source here.

All you need to do is register this class to your SoapSerializationEnvelope.

Check out the code below,

private static final String NAMESPACE = "http://www.kltro.com";
private static final String METHODNAME = "getOutlets";
private static final String WSDL = "http://mapx.kashkan.org:5445/tro/ws/kltro";
private static final String SOAP_ACTION = NAMESPACE + "#kltro:" + METHODNAME;
private static String TAG = "soap_tester";

public static String callWebservice() {
    String responseDump = "";
    try {
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        // Register the Date Marshal class
        new MarshalDate().register(envelope);

        SoapObject request = new SoapObject(NAMESPACE, METHODNAME);
        request.addProperty("userId", "a24f0c23-5f36-11e4-b332-984be174a0cc");

        // Your date
        String dateStr = "2016-08-25";

        // Parse the date into an object of type java.util.Date
        SimpleDateFormat sdfIn = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);

        // You might want to play around with the timezones
        Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("ru"), Locale.ENGLISH);
        calendar.setTime(sdfIn.parse(dateStr));

        // Clear the hour, minute and second
        calendar.set(Calendar.HOUR, 0);
        calendar.set(Calendar.MINUTE, 0);
        calendar.set(Calendar.SECOND, 0);
        Date date = calendar.getTime();;

        // Create a property with the date object and type as java.util.Date.class
        PropertyInfo dateProperty = new PropertyInfo();
        dateProperty.setValue(date);
        dateProperty.setName("date");
        dateProperty.setType(Date.class);

        // Add it to the request
        request.addProperty(dateProperty);

        envelope.bodyOut = request;
        HttpTransportSE transport = new HttpTransportSE(WSDL);
        transport.debug = true;
        try {
            transport.call(SOAP_ACTION, envelope);
            String requestDump = transport.requestDump;
            responseDump = transport.responseDump;
            Log.e(TAG, requestDump);
            Log.e(TAG, responseDump);
        } catch (IOException e) {
            e.printStackTrace();
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
    return responseDump;
}

This is the requestDump,

<?xml version="1.0" encoding="UTF-8"?>
<v:Envelope xmlns:v="http://schemas.xmlsoap.org/soap/envelope/" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
   <v:Header />
   <v:Body>
      <n0:getOutlets xmlns:n0="http://www.kltro.com" id="o0" c:root="1">
         <userId i:type="d:string">a24f0c23-5f36-11e4-b332-984be174a0cc</userId>
         <date i:type="d:dateTime">2016-08-24T00:00:00.000Z</date>
      </n0:getOutlets>
   </v:Body>
</v:Envelope>

Good luck :)
