Ksoap2 cannot serialize exception on Android 2.2 (using user-defined object)

Question

I know that there are many posts on this issue. However they are builded on Android 3.0 or above (using AsyncTask). I couldn't find my solution. There is a problem about getting an information from a webservice. Here is my code:

package com.example.marport;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Date;
import java.util.Iterator;
import java.util.List;
import java.util.Vector;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.SoapFault;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TextView;

public class Ithalatfaturalama extends Activity implements OnClickListener {

    EditText KonteynerNo;
    DatePicker DatePicker;
    Button Sorgula;
    TextView TextResult;
    List<String> toBeSentList;
    Iterator<String> it;
    Date toBeSentDate;
    SoapObject request;
    SoapSerializationEnvelope envelope;
    HttpTransportSE aps;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ithalatfaturalama);
        defineVars();
        Sorgula.setOnClickListener(this);
    }

    private void defineVars() {
        KonteynerNo = (EditText)findViewById(R.id.etKonteynerBill);
        DatePicker = (DatePicker)findViewById(R.id.datePicker1);
        Sorgula = (Button)findViewById(R.id.bSorgulaBill);
        TextResult = (TextView)findViewById(R.id.tvResultBill);
        toBeSentList = new ArrayList<String>();
        request = new SoapObject(WSDefinition.NAMESPACE,WSDefinition.REPORTS);
        toBeSentDate = new Date();
        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    }

    @Override
    public void onClick(View v) {
        String containerInfo = KonteynerNo.getText().toString();
        toBeSentList.add(containerInfo);
        it = toBeSentList.iterator();
        String temp = (String) it.next();
        request.addProperty("ids",temp);

        int Day = DatePicker.getDayOfMonth();
        int Month = DatePicker.getMonth();
        int Year = DatePicker.getYear();

        toBeSentDate.setYear(Year);
        toBeSentDate.setMonth(Month);
        toBeSentDate.setDate(Day);

        request.addProperty("date",toBeSentDate);
        envelope.dotNet = false;
        envelope.setOutputSoapObject(request);

        try {
            aps = new HttpTransportSE(WSDefinition.URL);
            aps.call(WSDefinition.REPORTS_ACTION, envelope);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        try {
            @SuppressWarnings("unchecked")
            Vector<SoapObject> result = (Vector<SoapObject>) envelope.getResponse();
            Vector<MarportAgentReport> responseList = new Vector<MarportAgentReport>();

            for (SoapObject obj : result) {

                MarportAgentReport tmp = new MarportAgentReport(obj);
                responseList.add(tmp);
            }

            String resultStr = "";
            for (int i = 0 ; i < responseList.size();i++){
                MarportAgentReport tmp = responseList.get(i);
                resultStr += (i+1) +".Category = "+tmp.getCategory()+"\n";
                resultStr += (i+1) +".Container = "+tmp.getContainer()+"\n";
                resultStr += (i+1) +".InShip= "+tmp.getInShip()+"\n";
                resultStr += (i+1) +".IsoCode = "+tmp.getIsoCode()+"\n";
                resultStr += (i+1) +".Line = "+tmp.getLine()+"\n";
                resultStr += (i+1) +".Muhur = "+tmp.getMuhur()+"\n";
                resultStr += (i+1) +".OutShip = "+tmp.getOutShip()+"\n";
                resultStr += (i+1) +".Position = "+tmp.getPosition()+"\n";
                resultStr += (i+1) +".Service = "+tmp.getService()+"\n";
                resultStr += (i+1) +".Status = "+tmp.getStatus()+"\n";
                resultStr += (i+1) +".Terminal = "+tmp.getTerminal()+"\n";
            }
            TextResult.setText(resultStr);

        } catch (SoapFault e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }
}

And here is my object:

Thank you.

Answer 1

you need to write

string temp= sorgula.getText().toString();

inside try block to get data from string. likewise, you need to mention all fields that are called by you at server side.

It helped me.Hope it helps you too. :)
