java.util.Date to XMLGregorianCalendar

To convert a java.util.Date object to an XMLGregorianCalendar in Java, you can use the toGregorianCalendar method of the DatatypeFactory class. Here's an example of how to use this method to convert a Date object to an XMLGregorianCalendar:

import java.util.Date;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class Main {
    public static void main(String[] args) throws Exception {
        Date date = new Date();
        XMLGregorianCalendar calendar = DatatypeFactory.newInstance().newXMLGregorianCalendar(date.toInstant().toString());
        System.out.println(calendar);
    }
}

This will convert the Date object to an XMLGregorianCalendar using the default time zone.

Note that you will need to import the javax.xml.datatype package and catch the DatatypeConfigurationException that may be thrown when creating a new instance of DatatypeFactory.

You can also use the toGregorianCalendar method to convert a Calendar object to an XMLGregorianCalendar. To do this, you can use the following code:

import java.util.Calendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class Main {
    public static void main(String[] args) throws Exception {
        Calendar calendar = Calendar.getInstance();
        XMLGregorianCalendar xmlCalendar = DatatypeFactory.newInstance().newXMLGregorianCalendar(calendar);
        System.out.println(xmlCalendar);
    }
}

This will convert the Calendar object to an XMLGregorianCalendar using the calendar's time zone.
