RE: RE: HowTo: Display a standby page/message for lenghty

[gg...@e-tree.com]

Hi guys,
aren't we dealing with a server based framework implementing MVC pattern?
I mean: if your application receives a request you can respond via
different
pages (a http-refresh waiting page, an error page, a confirmation page etc)
corresponding to the state of a session bean implementing the business
process.
The Chris Wilson's way works fine but it's based on a page centric
application,
while struts is not ( or almost not necessarly )
Hope this help
Pino

there's no reason why you can't send back any type of page you want.  i was
not trying to promote a page centric vs. whatever mode of operation.  in
fact if you were sending stuff to a wap phone, the interaction i described
might not even work.  i was simply trying to explain how to show a
processing page that automatically goes to the results of the process once
it's done (at least in the http/html world).
