Parameters:

bean - The bean validation is being performed on.

va - The ValidatorAction used to retrieve validator information.

field - The Field object associated with the current field being validated.

errors - The Vector object used by DBForms to add errors to if any validation errors occur.

locale - The Locale object of the Request.

dbFormsErrors - DbForms Error class to retrieve error message in DbForm-Errors.xml format.

validateDate

public static boolean validateDate(Object bean,
                                   ValidatorAction va,

                                   Vector errors,
                                   Locale locale,
                                   DbFormsErrors dbFormsErrors)

Checks if the field is a valid date. If the field has a datePattern variable, that will be used to format java.text.SimpleDateFormat. If the field has a datePatternStrict variable, that will be used to format java.text.SimpleDateFormat and the length will be checked so '2/12/1999' will not pass validation with the format 'MM/dd/yyyy' because the month isn't two digits. If no datePattern variable is specified, then the field gets the DateFormat.SHORT format for the locale. The setLenient method is set to false for all variations.

Parameters:

bean - The bean validation is being performed on.

va - The ValidatorAction used to retrieve validator information.

field - The Field object associated with the current field being validated.

errors - The Vector object used by DBForms to add errors to if any validation errors occur.

locale - The Locale object of the Request.

dbFormsErrors - DbForms Error class to retrieve error message in DbForm-Errors.xml format.
