Cocoon is a servlet-based application.

Just install a cocoon distribution into your WEB-INF directory of your WAR file:

1. Copy all the distribution files/directory into the WEB-INF directory.

2. Make sure that the 'sitemap' element points to your sitemap.xmap file in the WEB-INF directory:

   <sitemap check-reload="yes" 
            config="resource://org/apache/cocoon/components/treeprocessor/treeprocessor-builtins.xml" 
            file="context://WEB-INF/sitemap.xmap" 
            logger="sitemap"/>
   

3. Setup your sitemap.xmap file in WEB-INF (see Cocoon documentation).

Cocoon has many, many extra "kits" that provide optional features.

Everything is about 31MB.

I've trimmed this down to about 15MB.
