Cocoon integrate in a MVC2 environment?
Hi!
I evaluate cocoon for a big web application which based on the MVC2
(http://de.wikipedia.org/wiki/MVC#MVC_2) and I have one question:
It is posible cocoon to integrate in an existing MVC2 environment. It
means that cocoon addressed by a own controller.
I hope somebody has a answer.
Regards,
Hendrik

..thanks for your tips, I think I will take a closer look at the cocoon bean..

I'd try to refactor the custom controller and make it independant from having to
be a servlet. Then I would write a wrapper action (Cocoon action) that accesses
the custom controller and the action could call the required pipelines.
If you want to go the other way, the Cocoon bean seems to be the best bet. The
only problem I see is, how you can pass your model to the view layer. I've never
used the bean so far. Maybe you should ask this on dev@cocoon.

Thanks for the proposal.
But this fails, because my web app is to large for such design
changes. I need a minimal invasive solution which only concerns some
publishing output.

Note that if you only want to use Cocoon's publishing features, you
could do the opposite: put Cocoon in front of your app, have your app
output XML (serialized objects in whatever format) and use the Cocoon
pipelines to do the presentation.
You'll need to use something like the HttpProxyGenerator so that
request parameters are correctly relayed to the backend, and some
assembly might be required depending on the interactions between your
client and current application. But it's certainly worth trying.

Ok, I have read many articles about cocoon and "Probably yes" was my
first cognition :-), but after the first steps with cocoon I have the
sense that I must build my complete web application with cocoon
although I only need the great publishing functions of cocoon.

The existing environment has one central servlet and many controllers.
The presentation of the database content is handled by JSPs and
taglibs. My wish is that controllers for the publishing stuff use
cocoon to allow a better separation of content, style and logic. But
how can I address cocoon from a controller?
Perhaps is the CocoonBean a solution?
Thanks and regards,
Hendrik

Probably yes. You will need to write some "glue" code. In order to get more
precise answers, you'll have to tell use more about the existing environment.
