    <p>i am using <strong>ksoap2</strong> (ksoap2-android-assembly-3.0.0-RC.1-jar-with-dependencies.jar) to communicate my <strong>android</strong> app with soap service which is set up on <strong>jboss 7</strong> (jboss-as-7.1.1_Final &amp; jbossws-cxf-4.0.2.GA) with <strong>jaxws</strong>-2.2.6-2-20120518.</p> <p>I am able to fetch any data (any means my custom objects) but i am not able to send them through. I have followed <a href="http://seesharpgears.blogspot.com/2010/10/ksoap-android-web-service-tutorial-with.html" rel="nofollow">this</a> article. My object (named "Frame") is implementing org.ksoap2.serialization.KvmSerializable.</p> <p>My request wrapper class looks like:</p> <pre><code>@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; } } </code></pre> <p>When i try to send object (not inside android) using java se methods (javax.xml.namespace.QName &amp; javax.xml.ws.Service) object is persisted in my mssql database, so i think there is some problem with my android client implementation.</p> <pre><code>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); </code></pre> <p>After this i receive:</p> <ul> <li>android log:</li> </ul> <pre> 07-22 16:48:51.256: E/FRAME(1013): eu.i2.android.delegate.exception.DelegateException: SoapFault - faultcode: 'soap:Client' faultstring: 'Unmarshalling Error: null '

    1. COSomehow 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.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
