Of course my code *doesn't* work, but I'll leave the reason why as an
exercise for the reader ;}

Hi,
I just happened to be working on this problem myself. I wrote a validator:
public class dateValidation implements Serializable {
private static final Log log = LogFactory.getLog(dateValidation.class);
/* checks two date fields to see if the second field isn't earlier than
* the first field.
* Use in combination with Date validator to make sure date format is
correct.
*/
public static boolean beginEndDate(Object bean,
ValidatorAction va, Field field,
ActionMessages errors,
Validator validator,
HttpServletRequest request){
Date beginDate = null;
Date endDate = null;
String dateBegin = ValidatorUtils.getValueAsString(bean,
field.getProperty());
String sProperty2 = field.getVarValue("endDate");
String dateEnd = ValidatorUtils.getValueAsString(bean, sProperty2);
String datePattern = field.getVarValue("datePattern");
SimpleDateFormat sdf = new SimpleDateFormat(datePattern);
try{
beginDate = sdf.parse(dateBegin);
endDate = sdf.parse(dateEnd);
}
catch (ParseException e){
if (log.isDebugEnabled()) {
log.debug("Date parse failed dateBegin =[" + dateBegin
+ "] dateEnd =["+ dateEnd + "], " +
"pattern=[" + datePattern +
"], " + e);
}
}
if (beginDate.compareTo(endDate) <= 0) return true;
return false;
}
}
you'll also need to add the following to validation-rules:
<validator name="beginEndDate"
classname="nl.sogyo.intranet.timesheets.customValidators.dateValidation"
method="beginEndDate"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
depends="date"
msg="errors.beginEndDate"/>
I haven't tested it yet, so I give no guarantees.

from a Java class and a custom validator seems like a good place. Considering it
gives you access to a bunch of objects for free like the form bean, fields, the
request object, errors object etc. You could probably do it in a separate class
cueing off of the data from the form bean, but I think it would be much harder.

then I agree with you in that I need to write my own custom validator easily. But
I prefer if Struts already has this sort of comparison validator.

In your custom validator, create 2 calendars, one each for start date and end date. Then use the
method call "before" or "after" on these calendar.
