Errors from within Action.perform()

Struts encourages two different ways to do form validation:  inside the
ActionForm.validate() method (presumably for low-level field validation) and
in the Action.perform() method (presumably for higher-level business logic
validation).  ActionForm.validate() lets me return an ActionError object
that displays error messages on the JSP.  Is there a way for me to leverage
this same error architecture from within my Action.perform() method?

In other words, how can I generate error messages in my Action that will
display on the JSP, in exactly the same way that errors from my
ActionForm.validate() method can?  Is it somehow possible to generate an
ActionErrors object from inside an Action.perform() method?

Thanks.

Thanks.  Somehow I missed the "saveErrors()" method in the Action class, but
that looks like it will do what I want.

  this should work.

  this is also there in struts example  "SaveRegistrationAction"

   errors.add("somestring",
                             new ActionError("error.key"));
   }

   if (!errors.empty()) {
       saveErrors(request, errors);
       return (new ActionForward(mapping.getInput()));
   }

  hope this helps
