ksoap - request response object mapping

Question

I am getting the following error when I try to call a web service described by a hosted wsdl.

"Unable to un-marshall between the XML Document and JAXB Objects."
'org.xml.sax.SAXException: Unable to un-marshall between the XML Document and JAXB Objects.  See server logs for more details.
null' faultactor: 'null' detail: org.kxml2.kdom.Node@6782a9
    at org.ksoap2.serialization.SoapSerializationEnvelope.parseBody(SoapSerializationEnvelope.java:137)
    at org.ksoap2.SoapEnvelope.parse(SoapEnvelope.java:140)
    at org.ksoap2.transport.Transport.parseResponse(Transport.java:129)
    at org.ksoap2.transport.HttpTransportSE.parseResponse(HttpTransportSE.java:301)
    at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:274)

Actually I am testing the ksoap library in a JAVA program and not android. Once this test passes I am planning to migrate the code to Android. But since the error is occurring during un-marshalling, I assume the service call is happening and there is an issue with parsing the response.

Below is my Java program I am testing with:

package com.tc.wsdl.runner;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Hashtable;
import java.util.List;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpResponseException;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import com.tc.ws.client.session.InternalServerException;
import com.tc.ws.client.session.InternalServerFaultFault;
import com.tc.ws.client.session.InvalidUserFaultFault;

    {
        // TODO Auto-generated method stub
        try
        {
            ksoapGetAvailableServices();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

    }

        PropertyInfo propInfo = new PropertyInfo();
        propInfo.name = "getAvailableServicesRequest";
        propInfo.setValue(input);
        propInfo.type = GetAvailableServicesInput.class;
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty(propInfo);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.implicitTypes = true;

        envelope.setOutputSoapObject(request);

            this.serviceNames = serviceNames;
        }

    }

}

Below is the stripped out WSDL. I have kept the parts related to the service operation - getAvailableServices - I am calling in the below wsdl:

Kindly help in identifying the mistake I have made.

The GetAvailableServicesResponse class is similar to the one generated through wsimport. But I want this to work in Android so I am avoiding all external libraries except ksoap-with-dependencies jar in classpath. So the response object contains a list of String.

I have added the namespace mapping also as updated in the code. I tried both the namespaces xmlns:tns and xmlns:imp2. Still getting the same Un-marhsall error while parsing the response. Is there a way to get the response XML that the ksoap library is trying to parse?
