You need to add an error message when validation fails:
if (beginDate.compareTo(endDate) <= 0) return true;
ActionMessage msg = Resources.getActionMessage(validator, request,
va, field);
errors.add(field.getKey(), msg);
return false;

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.

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.
