see http://jakarta.apache.org/commons/betwixt/guide/binding.html for more details.
as for good example, i'm sad to say that the ones in the user guide are the best we have. improvement would be most gratefully received.
BTW for these features you need to upgrade from 0.5 to CVS HEAD, a recent nightly or the release candidate for 0.6.

hi, robert Thanks for you help very much!
But still I can not use it well. I tried a custom ObjectStringConverter and
did not get the output I wished.
My problem is: how to eliminate some object in the output? (Since I do want
to show other null object in the
output XML, I can not use "setWriteEmptyElements" to do that.)
Could you show me some good samples of that?
// ==================================== // Here is the converter I used // ==================================== public class MyConverter extends ConvertUtilsObjectStringConverter { public String objectToString(Object object, Class type, String flavour, Context context) { if ( object == null ) { return ""; }
if ( Calendar.class.equals(context.getBean().getClass()) || GregorianCalendar.class.equals(context.getBean().getClass()) ) { if (Date.class.equals(type)) {
DateFormat dateFormat = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss.SSS z''");
dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
String myTime = dateFormat.format((Date) ((GregorianCalendar) context.getBean()).getTime()); return myTime; } return ""; }
if ( ZoneInfo.class.equals(context.getBean().getClass()) ) {
context.setBean(null);
return "";
}
return ConvertUtils.convert( object ); }
public Object stringToObject(String value, Class type, String flavour, Context context) { ...... } }
// ==================================== // Here is the output I got // ==================================== <MyBean> ...... ...... ...... <myCal> <firstDayOfWeek/> <gregorianChange>'2004-09-21 13:11:04.234 UTC'</gregorianChange> <lenient/> <minimalDaysInFirstWeek/> <time>'2004-09-21 13:11:04.234 UTC'</time> <timeInMillis/> <timeZone> <DSTSavings/> <ID/> <displayName/> <rawOffset/> </timeZone> </myCal> ...... ...... ...... </MyBean>
// ==================================== // and Here is the output I wished // ==================================== <MyBean> ...... ...... ...... <myCal>'2004-09-21 13:11:04.234 UTC'</myCal> ...... ...... ...... </MyBean>

(hopefully better late than never)
yes: use a custom object <-> string converter. see http://jakarta.apache.org/commons/betwixt/guide/binding.html for more details.

hi, I am a beginner of commons.betwixt. I just wondering if Betwixt can do this and how : when convert a Bean To Xml, Could betwixt recognize an object in the bean I input, and then change the output of it to another object(exp : Date) in the XML?
FOR EXAMPLE : >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> If there is a Calendar in myBean, could Betwixt just write it as a Date in the output XML? // ==================================== // If the Bean for convert is => // ==================================== public class MyBean {
private String id; private String name; private String[] emails; .......... private Calendar myCal;
..........
}
// ==================================== // The output XML I hoped is => // ==================================== <?xml version='1.0' encoding='UTF-8'?> <mybean> <String>id value</String> <String>name value</String> <String>email value</String> .......... <Date>Date value</Date> .......... </mybean>
