Bill,
Thanks for your reply. I was trying to write a custome validation method to
see whether it is working or not. I checked the method definition
(validateInt) and the declaration (int) in the validator-rules.xml and it
looks same.
Here is the sample code. I removed the generic validation methods to make it
simple. Thanks Siva
------ validator class --
public static boolean validateInt(Object bean,ValidatorAction action,
Field field,ActionErrors errors,HttpServletRequest request) {
String value = ValidatorUtils.getValueAsString(bean,
field.getProperty());
boolean isFieldValid = false;
try {
Integer.parseInt(value);
isFieldValid = true;
} catch (Exception e) {
errors.add(field.getKey(), Resources.getActionError
(request, action, field));
isFieldValid = false;
}
return isFieldValid;
}
---------- validation-rules.xml ---------

</global>
</form-validation>
