sorry

[Roman Seidl <rs...@pvl.at>]

Hello cocoon-users,

  im really sorry about the last two messages concerning session status
  - i keep confusing terms - heres a corrected version that should
  finally be somehow understandable

---------

the only thing im still thinking about is how to use some simmilar mechanism
in a processor - as i dont want to put big amounts of buisness logic
into a producer - id rather like to hide the buisness logic in a
processor because then id have some kind of universal xml interface not
bound to use servlet technology

i think ill have to implement a persistent session object for a
processor myself - maybe there's someone else who would like this idea?

Well, Cocoon v2 I think will have more abstraction away from just servlets.
I haven't looked at the source yet but this may be more along the lines of
what you're looking for although Cocoon 2 is still a ways off.

I'm not sure how Cocoon handles binary data

I know. I want to rely on servlet technology regarding wap or http -
but there might be more - well maybe you are right - maybe my ambition
to use as much abstraction as possible is a bit too much.

I have an existing groupware application that provides several services
like workspaces, email, user rights, voting etc. . The core is acessed
via corba - you just create a user session and ask for the information
you want or call a function. I have been thinking of using xml for
a month now and im still not sure what design approach to use. using
cocoon still seems like a good idea to me - but theres several
problems concerning cocoon:
- i have to have a persistent session (no problem in a producer but im
  not sure wether i want to use a producer for the buisness logic)
- i have to serve binary data like files uploaded by users, voice
  messages or bitmaps

If you don't want anything to rely on servlets than you'll have to create
your own session mechanism as Cocoon does not have any way to keep state.
But this begs me to ask why you're using Cocoon if you don't want to rely on
servlets?? Cocoon IS a servlet.
