Send an array of complex objects using ksoap2 to .NET web service

Question

Hi

I am facing a problem in sending an array of complex object from a J2ME Client using KSOAP to .net web service (Soap services).

my TestSoap.java file has a setArr() method which takes an array of PropHeaderMapBin object and sends it to the web service which returns an integer (count of PropHeaderMapBin objects)

TestSoap.java

package org.tempuri;

    import com.n9ciphers.test.Constants;
    import java.util.Vector;
    import org.ksoap2.SoapEnvelope;
    import org.ksoap2.serialization.PropertyInfo;
    import org.ksoap2.serialization.SoapObject;
    import org.ksoap2.serialization.SoapSerializationEnvelope;
    import org.ksoap2.transport.HttpTransport;
    import org.tempuri.PropHeaderMapBin;

    public final class TestSoap {

        public int setArr(PropHeaderMapBin[] inArr) throws Exception {

            SoapObject _client = new SoapObject("http://tempuri.org/", "SetArr");
            SoapObject[] _propHeaderMapBinSO = new SoapObject[inArr.length];

            PropHeaderMapBin[] prop = inArr;
            //PropHeaderMapBin[] prop = new PropHeaderMapBin[inArr.length];
            Vector _propVector = new Vector(inArr.length);
            if (inArr != null) {

                //System.out.println("_len  " + inArr.length );

                for (int i = 0; i < inArr.length; i++) {
                    _propHeaderMapBinSO[i] = new SoapObject("http://tempuri.org/", "PropHeaderMapBin");
                    _propHeaderMapBinSO[i].addProperty("PropertyName", prop[i].getPropertyName());
                    _propHeaderMapBinSO[i].addProperty("value", prop[i].getValue());
                    _propHeaderMapBinSO[i].addProperty("HeaderText", prop[i].getHeaderText());
                    _propHeaderMapBinSO[i].addProperty("label", prop[i].getLabel());

                    _propVector.addElement(_propHeaderMapBinSO[i]);
                }
            }

            _client.addProperty(pi, _propVector);

            SoapSerializationEnvelope _envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            _envelope.addMapping("http://www.tempuri.org/", "PropHeaderMapBin", new PropHeaderMapBin().getClass());
            //_envelope.addTemplate (_client);
            _envelope.bodyOut = _client;
            _envelope.dotNet = true;

            HttpTransport _ht = new HttpTransport(Constants.endPoint + "Test.asmx");
            _ht.debug = true;
            _ht.call("http://tempuri.org/SetArr", _envelope);

            //System.out.println("response: " + result.toString());

            System.out.println("Request Dump:" + _ht.requestDump);
            //Dialog.show("Request Dump", _ht.requestDump, Dialog.TYPE_INFO, null, "OK", null);
            System.out.println("Response Dump:" + _ht.responseDump);
            //Dialog.show("Response Dump", _ht.responseDump, Dialog.TYPE_INFO, null, "OK", null);

            return Integer.parseInt(_envelope.getResponse().toString());
            //return 0;
        }
    }

Output of setArr() method call. the server does not recognize the datatype of the objects in array and it sets the arraytype to anytype[3] and returns a 0 instead of 3.

I wud appreciate any help if some one has already faced this kind of issue and resolved it successfully.

Answer 1

I can give you hint to solve a problem.

using soapUI tool create web service project with same WSDL (it is very easy and fast).

Compare your request dump with soap body generated by soapUI. You will find out the difference and

hence solution.
