Ao utilizar os WebServices via Java™, deve-se atentar para o tipo de cada atributo e para o tipo de retorno do WebService. Por exemplo, para valores do tipo data deve ser utilizado a classe XMLGregorianCalendar:

DocumentDto document = new DocumentDto();

XMLGregorianCalendar date = DatatypeFactory.newInstance().newXMLGregorianCalendar();
date.setYear(2013);
date.setMonth(10);
date.setDay(16);
date.setHour(0);
date.setMinute(0);
date.setSecond(0);

document.setExpirationDate(date);
