Here is a Calendar converter class. Modify as necessary for your calendar
object:

import java.util.GregorianCalendar;
import java.util.Map;
/**

Standard Format*/
String[] parsePatterns = {
"MM/dd/yyyy hh:mm a",
"MM/dd/yyyy hh:mm:ss a",

"MM/dd/yyyy HH:mm",
"MM/dd/yyyy HH:mm:ss",
"dd-MMM-yyyy HH:mm",
"dd-MMM-yyyy HH:mm:ss",
"MM/dd/yyyy",
"dd-MMM-yyyy"
};
FastDateFormat df = FastDateFormat.getInstance(parsePatterns[0]);
if (aClass == Calendar.class) {
/********************************************************Get
First Value in Parameters Array*/
String source = ((String[]) object)[0];
/********************************************************Create
Target Calendar Object******/
Calendar returnCal = new GregorianCalendar();
Date transfer;

DateUtils parse with array of patterns*/
/********************************************************Currently only one
pattern that forces the time to be*/
/********************************************************present. Could
include a MM/dd/yyyy pattern but you*/
/********************************************************should use a
java.util.Date object for that type*/
transfer = DateUtils.parseDate(source, parsePatterns);

returnCal.setTime(transfer);
return returnCal;
} catch (ParseException e) {
throw new RuntimeException("Cannot convert " + source + " to
calendar type");
}
