Sending custom objects with kSOAP

Question

i am using ksoap2 (ksoap2-android-assembly-3.0.0-RC.1-jar-with-dependencies.jar) to communicate my android app with soap service which is set up on jboss 7 (jboss-as-7.1.1_Final & jbossws-cxf-4.0.2.GA) with jaxws-2.2.6-2-20120518.

I am able to fetch any data (any means my custom objects) but i am not able to send them through. I have followed this article. My object (named "Frame") is implementing org.ksoap2.serialization.KvmSerializable.

My request wrapper class looks like:

@XmlRootElement(name = "addFrame", namespace = "http://frame.service.server.android.i2.eu/")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "addFrame", namespace = "http://frame.service.server.android.i2.eu/")
public class AddFrame {

    @XmlElement(name = "arg0")
    private Frame frame;

    public Frame getFrame() {
        return frame;
    }

    public void setFrame(Frame frame) {
        this.frame = frame;
    }
}

When i try to send object (not inside android) using java se methods (javax.xml.namespace.QName & javax.xml.ws.Service) object is persisted in my mssql database, so i think there is some problem with my android client implementation.

String namespace = "http://frame.service.server.android.i2.eu/";
String wsdl = "http://localhost:8080/AndroidServer/AndreyServices/FrameService?wsdl";
String action = "addFrame";
String method = "http://frame.service.server.android.i2.eu/addFrame";

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

SoapObject request = new SoapObject(namespace, action)

PropertyInfo info = new PropertyInfo();
info.setType(Frame.class);
info.setValue(frame);//frame as a java method parameter
info.setName("arg0");
request.addProperty(info);

envelope.setOutputSoapObject(request);

HttpTransportSE soapCall = new HttpTransportSE(wsdl);
soapCall.call(action, envelope);

After this i receive:

I did not install any jar from here in jboss modules.

Thank You in advance!

Somehow the problem is not present anymore... I actually do not know what i have done. Yet i am facing another. When i receive an object on the server side it is empty - every single field is null. — czaaja, Jul 23 '12 at 16:27
Switch on debugging and look at the response and request dumps and see if they look as expected and try them in an external tools for starters. — Manfred Moser, Jul 25 '12 at 19:53

the null in android client is missing SoapObjects extend in class, I recommend also using CXF client on android as this generates automatically classes.

This problem of every single field being null is mostly due to a NameSpace problem. The data you are sending through SOAP is not being mapped to the object elements on the server side, hence they are null/zero.

I would suggest playing around with the namespace.

It would be more helpful for us to give a definite answer if you post your WSDL code here.

Also have a look at my solution, I had a similar problem.

passing objects to wcf soap service from android using ksoap2; it sends and receives 0

Thank You for Your answers.

I have managed to fix my problem by simply writing marshaller class which implements org.ksoap2.serialization.Marshal. After that CXF interceptors streams were build properly and SOAP envelopes were serialized correctly so I have moved my implementation to android project.
