i have created a function in class:

public static boolean validateSSN(Object bean , ValidatorAction action , Field field , ActionErrors errors , HttpServletRequest request)
{
String value = ValidatorUtil.getValueAsString bean,field.getProperty());
if( (value == null) || (value.length()<5))
{
errors.add(field.getKey(),Resources.getActionError (request,action,field));
return false;
}

return true;
}

Please tell me that what would be the reason for this.

Thanks
