Thanks Mark !

In my case removing the insert="false" update="false" fixed the problem.

You can use this:

DatatypeFactory df;
try {
df = DatatypeFactory.newInstance();
return df.newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"));
} catch (DatatypeConfigurationException e) {
throw new SomeRuntimeException(e);
}
