redirects / actionErrors

[mucus snot <mu...@virgin.net>]

Hi,

I am using action errors as a means of passing messages to the request:

e.g.

in Action, execute method...

errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("message.to.user"));
saveErrors(request, errors);
return mapping.findForward(Constants.REDIRECT_KEY);

But if I redirect from this action to another forward that is also an 
action, the actionError is out of scope.

I would be interested to know if
(a) this is good practice - to forward to another forward (it seems to work 
for me)
(b) there is an easy way to carry the actionError forward within storing in 
the session, and saving it in the redirected request.

Hope I'm making sense,

Thanks, al

    Hi,

    I don't know if i could understand your doubt (correct me if i'm 
wrong) but you must "forward" to your .jsp page and not "redirect"...

    If you have a global forward (in your struts-config.xml) like

<forward name="/my_forward_name" path="/my_jsp.jsp" redirect="false"\>

    the request will be "forwarded" to the .jsp resource. But if you have

<forward name="/my_forward_name" path="/my_jsp.jsp" redirect="true"\>

    the request will "redirected" (then you will "lose" the attributes 
in your request)

Struts 1.2 has a feature you can use that allows you to store your
ActionMessages in session variables, then have it removed once they're
accessed.  I haven't used this yet, but you can probably build on this by
storing your errors before you redirect, then have them displayed by the
resource your redirected to.
Another option is the extensions at http://www.rabago.net/struts/redirect
which actually adds your messages (error or not) to the url paramters and
puts them back on the ActionMessages queue upon redirection.
