org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.

Ciao a tutti!
Ho un problema che mi sta bloccando: sto cercando di comunicare con un web service di un cliente utilizzando il JDK 1.5 e Axis 1.4.
Più sotto ci sono il WSDL del web service e il codice java col quale cerco di invocarlo.
Putroppo ottengo sempre lo stesso risultato: "org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. "

Credo di aver capito che il SimpleDeserializer non riesce a deserializzare dei dati di input che non siano tipi primitivi... ma questo non mi risolve il problema ;-)

Qualcuno sa dirmi per favore dove sto sbagliando?!?!
Grazie mille!!!!!!!
Ciao,
Mirko

codice:
try {
     String nomeMetodo = "make";

     call.setTargetEndpointAddress(new URL                         ("http://www.meridiana.it/webservices/ws_search.asmx"));

     String XMLSecurityAccess = createXMLSecurityAccess(); // stringa in formato XML
     String XMLInputDataDetail = createXMLInputDataDetail(); // stringa in formato XML

     TWsInputData myTWsInputData = new TWsInputData(); // semplice oggetto con 2 proprietà String
     myTWsInputData.XMLSecurityAccess = XMLSecurityAccess;
     myTWsInputData.XMLInputDataDetail = XMLInputDataDetail;

     QName qn = new QName( "DsFlightSearch", "TWsInputData" ); 
     call.registerTypeMapping(TWsInputData.class, qn,
     new org.apache.axis.encoding.ser.BeanSerializerFactory(TWsInputData.class, qn), 
     new org.apache.axis.encoding.ser.BeanDeserializerFactory(TWsInputData.class, qn));

     call.setSOAPActionURI("http://tempuri.org/" + nomeMetodo);
     call.setUseSOAPAction(true); 
     call.setOperationName(nomeMetodo);
