Tomcat + Cocoon (as only a renderer)

[suplizio <su...@blarg.net>]

Total newbie here. I've spent a great amount of time on the requisite
How-to's and tutorials but I am still, however, facing some
configuration issues that I could use help with. I have a large,
complex servlet-based app using Tomcat 4.1, j2sdk1.4.2_05 and I want to
use and Cocoon 2.1.7 to handle all the presentation layer rendering. In
managing this, I do not want to go through the Cocoon servlet, but
rather would like to continue to manage all session data through our
current master servlet. 

So far, I've discovered that all webapps that use Cocoon must reside in
$CATALINA_HOME/webapps/cocoon/<myapp>. Is there a way to keep my
current app at $CATALINA_HOME/webapps/<myapp>, serve it up as is but
only leverage Cocoons rendering capabilities? I hope that makes sense.

If someone please point me into a direction where I read about using
Cocoon without making my current application entirely a Cocoon app I'd
appreciate it.

Respect,
J

I'm not sure I understand the whole question, but I can tell you that 
not all Cocoon apps have to reside under $CATALINA_HOME/webapps/cocoon/. 
You can put map:mount entries in your Cocoon sitemap, or in a separate 
mount table, to point to Cocoon apps anywhere. Nor does Cocoon itself 
need to reside in $CATALINA_HOME/webapps/cocoon/; you can set the path 
attribute on the Context element in your Tomcat conf/server.xml file to 
point anywhere.

But I'm not sure what Cocoon apps' location on the disk has to do with 
using your current servlet-based app with Cocoon. As I understand it, 
you want your servlet-based app to "call" Cocoon for presentation layer 
rendering. If your app can do a GET on a URL and receive the response, 
then your app can call Cocoon pipelines, e.g. via 
http://localhost/cocoon/myCocoonRendererApp/params. Then it doesn't 
matter where Cocoon resides on disk, it only matters how Cocoon and 
Tomcat are configured to process URLs.

Am I understanding your question right? If you can elaborate, I can 
probably provide more details.
