Error while accessing webservice using generated stub

Question

I want to consume a webservice which supplies information about countries:
http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL
I have generated a Webservice stub using JDeveloper. It supplies me with the right interface, but when I use the stub to access the webservice, I encounter an error:
java.lang.ClassCastException: oracle.xml.parser.v2.XMLText
     at oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub.fromElement(WrappedDocLiteralStub.java:614)
     at mypackage3.CountryInfoServiceStub2.CapitalCity(CountryInfoServiceStub2.java:72)
     at mypackage3.callWS.main(callWS.java:19)
I have checked the response message, but it is all right. With "some" handcoding , I can extract the answer I want out of the response XML. It seems, that the stub fails to cast the response to the right result class.
The method I use from the stub generated by JDeveloper. The error occurs at the last line, where the content of the message should be cast to String :
=========================================================
public String CapitalCity(String sCountryISOCode) throws Exception
URL endpointURL = new URL(_endpoint);
Envelope requestEnv = new Envelope();
Body requestBody = new Body();
Vector requestBodyEntries = new Vector();
String wrappingName = "CapitalCity";
String targetNamespace = "http://www.oorsprong.org/websamples.countryinfo";
Vector requestData = new Vector();
requestData.add(new Object[] {"sCountryISOCode", sCountryISOCode});
requestBodyEntries.addElement(toElement(wrappingName, targetNamespace, requestData));
requestBody.setBodyEntries(requestBodyEntries);
requestEnv.setBody(requestBody);
Message msg = new Message();
msg.setSOAPTransport(m_httpConnection);
msg.send(endpointURL, "", requestEnv);
Envelope responseEnv = msg.receiveEnvelope();
Body responseBody = responseEnv.getBody();
Vector responseData = responseBody.getBodyEntries();
return (String)fromElement((Element)responseData.elementAt(0), java.lang.String.class);
=========================================================
The class I use to call the webservice:
=========================================================
package mypackage3;
public class callWS
public callWS() {  }
public static void main(String[] args)
{  System.out.println("Calling CountryInfo Webservice");
try
CountryInfoServiceStub2 ws1 = new CountryInfoServiceStub2();
String capitalCity = ws1.CapitalCity("IT");
System.out.println("Capital City=" + capitalCity);
} catch (Exception exception)
{   System.out.println("An error occured while calling CountryInfoStub2:" );
exception.printStackTrace(System.out);
=========================================================

Hi dickdral
I', afraid I have not solution but the same problem. Today I try use VIES (http://ec.europa.eu/taxation_customs/vies/api/checkVatPort)
and the same exception occurs. Stub was generated by JDev 10.1.2.
Do you resolve this problem?
Thanks
