C2 and Avalon
Hi folks,
now that the beta is out, what is the relation of Cocoon2 and Avalon? We
already use Avalon here for other stuff, can we just install Cocoon as a
block or do we still need Tomcat?

No. We include the distribution jars from the Avalon web site:
jakarta.apache.org/avalon

There is a possibility of that. The interface does need to be thought out
though.

Avalon is split into six subprojects now. The reason is that Avalon was
too big, and covered too many different things--so we have them separated
out: Framework (the overall framework), Excalibur (reusable components),
LogKit (logger), Testlet (testing framework), Phoenix (server kernel),
and Cornerstone (reusable blocks).
Cocoon makes use of Avalon Framework, Avalon Excalibur, and Avalon LogKit.

We are probably still eligible for another round of questions !-)

Ahh. I am writing a paper that goes into serious depth on it--I will know if my
presentation is accepted for ApacheCon on Monday (or, at least that's what the
site says....). You may find it useful. Either way, I will make this paper
publically available.

Really?
I must have been using an old version.
Installation instractions say that an additional init-param must be added:
extra-class - pointing to servlet.jar in Tomcat.
If it's not correct, then it must be removed from docs, isn't it?

Hmm... I compile Tomcat 4.0 out of CVS AS-IS and deploy my cocoon.war
file into it without changing ANYTHING of the Tomcat stuff.

The best way to start with Avalon and C2 is to install them and try :)
The installation procedure is much more easier than with C1 (at least in
Tomcat 3.3/4.0b5 and WebLogic 6 sp1) - you just copy cocoon2.war to your
webapp directory and restart your servlet container.
With Tomcat 3.3 - that's all. You get running C2 based on Avalon and you can
start your investigation from the welcome page.
With Tomcat 4.0b5 and WebLogic you will have to make a little additional
steps. (For Tomcat - you'll find instructions on the installation page on
the C2 site). For WL 6 I can tell you what to do if you are interested.

Yes, I'm just using Avalon as a catch-all phrase for the whole thing :)
I don't know too much about Avalon, though, haven't used it myself. But
my boss tells me I have to soon ;-)

Ok. In that case, you are familiar with the subproject breakdown of
Avalon.

The version we're using here was downloaded from CVS about a week ago.

It sounds like you have an older Avalon installation as it is. You may want
to look at it now--there is alot that is different. You won't be able to plug in
a Block from the current Avalon into an old installation.

Well, that is what I meant with copying the code :)

Yes, so that I can use an existing Avalon installation and just plug
Cocoon2 into it.

I'm not sure what you mean. I say no, we are not copying code (at least no
sources that would be a maintainance nightmare) we use Avalon the way it is
meant to be used (we only have the jar from Avalon but noting more).

Integration? As a Block?

There is no specific need of Tomcat. We try to make it work in any servlet
container (which supports spec. 2.2)

Could you explain in more detail what answers you are expecting?

So what you guys do is copy the code from the Avalon project and embed
that version into the Cocoon2 project?
Will that integration happen in the future?
Will the need for Tomcat go away and will users have to install Avalon
first, before installing Cocoon2?
If you answer "yes" three times, you're eligible for the next round of

So far C2 is not a Block. You still need Tomcat (IIRC Tomcat 4 can be build as a
Block). The relation to Avalon is that C2 uses the framework and excalibur.

C2 does not have a Block interface, however the Cocoon object is a Component.
It would be trivial to create a block that implements the Processor interface
in Cocoon, with the Cocoon object as the implementor of the interface. The
major trick would be creating the Environment objects for Avalon.
