Answer Posted / mishra_pradip(geit)
ActionMessage: A class that encapsulates messages. Messages
can be either global or they are specific to a particular
bean property.
Each individual message is described by an ActionMessage
object, which contains a message key (to be looked up in an
appropriate message resources database), and up to four
placeholder arguments used for parametric substitution in
the resulting message.
ActionErrors: A class that encapsulates the error messages
being reported by the validate() method of an ActionForm.
Validation errors are either global to the entire
ActionForm bean they are associated with, or they are
specific to a particular bean property (and, therefore, a
particular input field on the corresponding form).
