If I can't write it in validator easily, then I write it in the validate()
method. I use validator for required, date mask, integer, and a few others.
If I knew anything about regular expressions or struts validator's validwhen()
I'd probably do more - excuses, excuses.
So, you could say something like:
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
log.info( request.getRemoteUser() + " *** validate - Start ***");
// Struts validator is happening here
ActionErrors errors = super.validate(mapping, request);
// I've seen examples that use null, but when I run it now, isEmpty() is
true and the errors object is not null)
if (( errors == null ) || errors.isEmpty() )
{
if (errors == null) errors = new ActionErrors();
// write your validation logic here, and set valid
if (!valid) {
// gain access to msg resource bundle...
MessageResources mr = (MessageResources)
request.getAttribute(Globals.MESSAGES_KEY);
// lookup any replace-able values to place into msg
String strArg0 = mr.getMessage("Page1.first_name");
//...
// Add msg to errors:
errors.add ( "property", new ActionMessage( "msg.key", strArg0
[,...] );
}
}
return errors;
}
If this is off base, then I'll assume someone else will chime in.
