Java and XML Date fields

If you use Xml Date and time field you will need to use the XmlGregorianCalendar

Easiest way to invoke this is.

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);

However if your Xml schema required separate Date and Time elements, not a single DateTime field then the following should be used. The standard XMLGregorianCalendar constructor used above will generate a DateTime field

Note there a couple of gothca's, such as having to add one to the month (since java counts months from 0).

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(yourDate);
XMLGregorianCalendar xmlDate = df.newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), 0);
XMLGregorianCalendar xmlTime = df.newXMLGregorianCalendarTime(cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND), 0);
