from XMLGregorianCalendar to Date/Calendar adds extra time/unwanted

Question

I’m developing a client to a web service which exposes (.wsdl) contract, which requires yyyy-MM-dd format for 1 on the request parameters , however auto generated POJOS based on the .wsdl create the date attribute as Type XMLGregorianCalendar.

---

My issue is NOT converting to or from XMLGregorianCalendar see my utility below:

public static XMLGregorianCalendar toXMLGregorianCalendar(Calendar c){
 GregorianCalendar gc = new GregorianCalendar();
 gc.setTimeInMillis(c.getTimeInMillis());
 XMLGregorianCalendar xc= null;
try {
    xc = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc);
} catch (DatatypeConfigurationException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
 return xc;
}

My issue is going from XMLGregorianCalendar to Date/Calendar adds extra time/unwanted data to my yyyy-MM-dd when calling calendar.getTime();

In a particular code segment I need to go from XMLGregorianCalendar to Date

if (repairOrderType.getCloseDate() != null) {

                LOG.debug("ServiceHistoryMapper, processRepairOrders() , repairOrderType.getCloseDate() BEFORE:"
                        + repairOrderType.getCloseDate());
                String date = repairOrderType.getCloseDate().getYear() + "-"
                        + repairOrderType.getCloseDate().getMonth() + "-"
                        + repairOrderType.getCloseDate().getDay();

                //Approach #1, trying to remove hour,minute,sec values by calendar.clear() method , not successful 
                Calendar calendar = Calendar.getInstance();
                calendar.set(repairOrderType.getCloseDate().getYear(),
                        repairOrderType.getCloseDate().getMonth(),
                        repairOrderType.getCloseDate().getDay());
                calendar.clear(Calendar.HOUR);
                calendar.clear(Calendar.MINUTE);
                calendar.clear(Calendar.SECOND);
                calendar.clear(Calendar.MILLISECOND);



                /*Approach#2 , trying to remove hour,minute,sec values using SimpleDateFormat ,
                 * also not successful. SimpleDateFormat or DateFormat are use to format String output NOT remove internal data
                 *
                DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
                Calendar calendar = formatter.getCalendar();
                calendar.set(repairOrderType.getCloseDate().getYear(),
                repairOrderType.getCloseDate().getMonth(),
                repairOrderType.getCloseDate().getDay());
                */

                LOG.debug("ServiceHistoryMapper, processRepairOrders() , repairOrderType.getCloseDate() AFTER:"
                        + calendar.getTime());
                repairOrder.setCloseDate(calendar.getTime());

            }

Output:

27-Nov-2012 18:10:39.743 DEBUG com.tms.owners.integration.nsh.mapping.ServiceHistoryMapper - ServiceHistoryMapper, processRepairOrders() , repairOrderType.getCloseDate() BEFORE:2012-04-30

27-Nov-2012 18:10:51.413 DEBUG com.tms.owners.integration.nsh.mapping.ServiceHistoryMapper - ServiceHistoryMapper, processRepairOrders() , repairOrderType.getCloseDate() AFTER:Wed May 30 18:00:00 PDT 2012

As you can see above BEFORE date is BEFORE:2012-04-30 and AFTER date is May 30 18:00:00 PDT 2012 with unwanted hours "18:00:00 PDT".

Below is my actual request XML sent to the service:

You can see in the request xml in the 2012-05-30-07:00 that extra "-07:00" data is added i just want 2012-05-30.

Thanks

Answer 1

The in context of XML datatypes the XMLGregorianCalendar is created via factory methods in javax.xml.datatype.DatatypeFactory which seems to have a method called newXMLGregorianCalendarDate(int year, int month, int day, int timezone);

---

So I created a utility method :

public static XMLGregorianCalendar toXMLGregorianCalendarDateOnly(Calendar c){
     GregorianCalendar gc = new GregorianCalendar();
     gc.setTimeInMillis(c.getTimeInMillis());
     XMLGregorianCalendar xc= null;
    try {
        xc = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(gc.get(Calendar.YEAR),Calendar.MONTH,Calendar.DAY_OF_MONTH,DatatypeConstants.FIELD_UNDEFINED);
    } catch (DatatypeConfigurationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
     return xc;
    }

The issue is resolved now, we are getting the desired yyyy-MM-ddd.

Answer 2

You can also write it in a following manner which is more readable:

GregorianCalendar gc = new GregorianCalendar();
gc.setTimeInMillis(c.getTimeInMillis());

XMLGregorianCalendar calendar = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc);
calendar.setMillisecond(DatatypeConstants.FIELD_UNDEFINED);
calendar.setTimezone(DatatypeConstants.FIELD_UNDEFINED);
