Hello.
I am using Castor to unmarshall a Java Bean class to an XML file.
The only fields that are not going to the XML file are the Calendar fields:
private Calendar effectiveDate;
public Calendar getEffectiveDate() {
return effectiveDate;
}
public void setEffectiveDate(Calendar aCal ) {
effectiveDate = aCal;
}
These fields are just being ignored.
When I generate the a mapping.xml file it also ignores these fields.
Any suggestions would be appreciated.

I believe java.util.Calendar is not among the "built-in" data types. Can you use java.util.Date instead? If not, you could try adding a mapping for java.util.Calendar into your mapping.xml file.

Hi.
Could you point me to a document that would explain how to
add java.util.Calendar to the mapping file ?
Ideally I would just like to map it once, as opposed to for each
field.
Thanks again.

The official documentation is all I know of. I'm not a Castor user myself, but I guess you'll have to take a look at the source code of the Calendar class to see all the private fields you have to include into the mapping file. (again, if it's possible to use java.util.Date instead...)

I still am not able to get my Calendar fields into my xml file.
Any suggestions would be appreciated.
Here is what I tried:
GeneralInfoRequest.java
private Calendar reviewDate_;
public Calendar getReviewDate() { return reviewDate_ ; }
public void setReviewDate( Calendar cal ) { reviewDate_ = cal; }
CalendarFieldHandler.java:
public class CalendarFieldHandler extends GeneralizedFieldHandler {
public final DateFormat format = new SimpleDateFormat("yyyy-MM-dd");


public Object convertUponGet(Object value) {
if ( value instanceof Calendar ) {
Calendar cal = (Calendar) value;

return format.format(cal.getTime());
} else {
return value;
}

}

public Object convertUponSet(Object value) {
String dateStr = (String) value;
Object result = null;
try {
Date date = (Date) format.parse(dateStr);
Calendar cal = new GregorianCalendar();
cal.setTime(date);
result = cal;

} catch (ParseException e) {

}
return result;
}
public Class getFieldType() {
return Calendar.class;
}
}
mapping.xml:
<?xml version="1.0" encoding="UTF-8"?>
<mapping xmlns="http://castor.exolab.org/" xmlns:cst="http://castor.exolab.org/">
<description>Castor generated mapping file</description>
<class name="services.types.GeneralInfoRequest" >
<field name="reviewDate" handler="ca.cooperators.tests.xml.mapping.CalendarFieldHandler"
type="java.util.Date" >
</field>
</class>
</mapping>

your last code is almost working (I know it's old)
you probably figured out since 2004 !

if you map with a string instead of a java.util.date
it works flawlessly

<field name="reviewDate" handler="ca.cooperators.tests.xml.mapping.CalendarFieldHandler"
type="string" >
</field>

just for other people coming to this thread
