kSoap2 POJO mapping class cast exception

Question

I have difficulties using kSOAP2 library for android. I am able to send requests and get the response, but I would like to map the contents of the response to a plain java object. Basically kSOAP2 allows you to do that by specifying the parameters of the mapping into the addMapping() method. Anyway I am having a class cast exception when trying to cast the response to my Java object. Here is my implementation :

final SoapSerializationEnvelope envelope = LoginInfo.buildLoginObject(login,password);
envelope.addMapping(NAMESPACE, "GetCustomerByIdPwdResponse", new GetCustomerByIdPwdResponse().getClass());

        new AsyncTask<Void, Void, Void>() {
            @Override
            protected Void doInBackground(Void... params) {
                HttpTransportSE httpTransport = new HttpTransportSE("URL");
                httpTransport.debug = true;

                try {
                    httpTransport.call(URL, envelope);
                    Log.d("SOAP OBJECT SENT",httpTransport.requestDump);
                    Log.d("SOAP OBJECT RESPONSE",httpTransport.responseDump);
                    GetCustomerByIdPwdResponse customerByIdPwd = (GetCustomerByIdPwdResponse)envelope.bodyIn;
                } catch (IOException | XmlPullParserException e) {
                    e.printStackTrace();
                }
                return null;
            }
        }.execute();

And here is the request and response I get, they are all good :

</s:Envelope>

And here is the error I get when trying to create my POJO :

11-18 11:36:57.967: E/AndroidRuntime(19208): Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to com.example.ksoaptest.GetCustomerByIdPwdResponse

Any help would be great since it's the last step to get me going towards my web service implementation.

Thanks !

UPDATE :

Here is my class for my customer. I now have an error when trying to map the customer to my RexUser class. I added the envelope.addMapping("rexwebservices","RexUser",RexUser.class); mapping to my envelope. I have an Caused by: java.lang.RuntimeException: Unknown Property: FirstName error when it comes to saving the customer data into the user object.

Answer 1

First make sure that namespace for most outer object in Your structure (GetCustomerByIdPwdResponse) is "rexwebservices", so adding mapping will be sth. like that:

envelope.addMapping("rexwebservices", "GetCustomerByIdPwdResponse", GetCustomerByIdPwdResponse.class);
envelope.addMapping("rexwebservices", "GetCustomerByIdPwdResult", GetCustomerByIdPwdResult.class);

Second thing - class that You defined is only outer box of Your response. I tried to define serializable of response and first level of Your structure. The response You included was correctly parsed to them.

public class GetCustomerByIdPwdResponse implements KvmSerializable {
    GetCustomerByIdPwdResult getCustomerByIdPwdResult;

        @Override
        public Object getProperty(int arg0) {
            if(arg0==0){
                return getCustomerByIdPwdResult;
            }
            return null;
        }

        @Override
        public int getPropertyCount() {
            return 1;
        }

        @Override
        public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
            if(arg0==0){
                arg2.name="GetCustomerByIdPwdResult";
                arg2.type=GetCustomerByIdPwdResult.class;
            }
        }

        @Override
        public void setProperty(int arg0, Object arg1) {
            if(arg0==0){
                getCustomerByIdPwdResult=(GetCustomerByIdPwdResult)arg1;
            }
        }
}

public class GetCustomerByIdPwdResult implements KvmSerializable {
    SoapObject Customer; //here goes Customer class ofcourse
    String ErrorMessage;
    String SessionId;

    @Override
    public Object getProperty(int arg0) {
        switch(arg0){
        case 0: return Customer;
        case 1: return ErrorMessage;
        case 2: return SessionId;
        }
        return null;
    }

    @Override
    public int getPropertyCount() {
        return 3;
    }

    @Override
    public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
        switch(arg0){
        case 0: arg2.name="Customer"; arg2.type=SoapObject.class;break; //Customer class
        case 1: arg2.name="ErrorMessage"; arg2.type=PropertyInfo.STRING_CLASS;break;
        case 2: arg2.name="SessionId"; arg2.type=PropertyInfo.STRING_CLASS;break;
        }
    }

    @Override
    public void setProperty(int arg0, Object arg1) {
        switch(arg0){
        case 0: Customer=(SoapObject)arg1;break;//Customer class
        case 1: ErrorMessage=(String)arg1;break;
        case 2: SessionId=(String)arg1;break;
        }
    }
}

I left Customer class for You - that is why Customer field in GetCustomerByIdPwdResult class is declared as SoapObject.

Hope it will help. Marcin
