}

I am not able to cast the response to the required purchase order class i guess 
it is some bug but i want to reconfirm is it my coding error or soemthing else

Hi The way i handle complex objects is as below snipplet. You can do nested for 
for every object, i have commited some changes to ksoap, and i will try to see 
the chances to implement something like this. but in the meantime you might 
want to check this approach.

PurchaseOrder responseArray[] = null;
    SoapObject _client = new SoapObject("", "soapMethod");
    SoapSerializationEnvelope _envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    _envelope.bodyOut = _client;
    KeepAliveHttpTransportSE _ht = new KeepAliveHttpTransportSE(JIRA_SERVER_URL, TIMEOUT, BUFFER_SIZE);
    _ht.call("", _envelope);

    Vector arr = (Vector) _envelope.getResponse();

    responseArray = new PurchaseOrder[arr.size()];

    for ( int i = 0; i < arr.size(); i++ ) {
        SoapObject _soapObject = (SoapObject)arr.get( i );

        int _len = _soapObject.getPropertyCount();
        PurchaseOrder _singleObject = new PurchaseOrder();
        for (int _i = 0; _i < _len; _i++) {
            _singleObject.setProperty(_i, _soapObject.getProperty(_i));
        }

        responseArray[i] = _singleObject;
    }
