Błąd przy konwersji daty xmlDataGregorianCalendar w pliku JSF

Błąd przy konwersji daty xmlDataGregorianCalendar w pliku JSF jak dokonać konwersji do potrzebnego formatu by edytować to w polu strony ?

 public AukcjaDTO getObiektAukcjaDTO() throws DatatypeConfigurationException {
        GregorianCalendar DataGregorianCalendar = new GregorianCalendar();
        DataGregorianCalendar.setTime(new Date(System.currentTimeMillis()));
        XMLGregorianCalendar xmlDataGregorianCalendar = DatatypeFactory.newInstance().newXMLGregorianCalendar(DataGregorianCalendar);
      
        ZiarnoAukcjaController.getRejestrowanieAukcja().setDataRozpoczecia(xmlDataGregorianCalendar);
        ZiarnoAukcjaController.getRejestrowanieAukcja().setDataZakonczenia(xmlDataGregorianCalendar);
        
        return ZiarnoAukcjaController.getRejestrowanieAukcja();
  }


<h:inputText id="dataRozpoczecia" value="#{dodajAukcje.obiektAukcjaDTO.dataRozpoczecia}" title="DataRozpoczecia" required="true" requiredMessage="The DataRozpoczecia field is required.">
                        <f:convertDateTime pattern="MM/dd/yyyy HH:mm:ss" />
</h:inputText>

generuje błąd

ok szybka wersja testowa do porawy ale działa

korzystałem z
