OK. I stopped Tomcat and removed the entire $TOMCAT_HOME/work folder and
restarted Tomcat. Everything looked fine in the Cocoon log files after
starting Tomcat until I attempt the first access of the main Cocoon start
page, then the log files start showing the following error lines (not all
are shown for brevity and bandwidth's sake):

Obviously these error messages in the log files are related to one another.
I double-checked the
'work/localhost_8080%2Fcocoon/cocoon-files/org/apache/cocoon/www' folder for
the sitemap_xmap files and found:
79221 Jul 25 13:44 sitemap_xmap.class
15470 Jul 25 13:44 sitemap_xmap$Configurer.class
339625 Jul 25 13:44 sitemap_xmap.java
These file appear to be fine. The file sizes are maintained through
delete/restarts.
I've commented out the X server stuff in sitemap.xmap.
I've followed the installation instructions on the Cocoon for 'Installing on
Tomcat 3.2.X' adding/removing lib files in Tomcat. My $TOMCAT_HOME/lib
folder has:
==========================================
330474 May 28 2001 ant.jar
217923 May 28 2001 jasper.jar
40810 May 28 2001 servlet.jar
4096 Jul 25 09:05 test
430434 May 28 2001 webserver.jar
1730053 Apr 11 14:30 xercesImpl-2.0.0.jar
108484 Apr 9 09:20 xml-apis.jar
136133 May 28 2001 zparser.jar
I've tried using a "unpackaged" Cocoon set of files as well as just copying
over the cocoon.war file (removing the /work/cocoon folder in between each
time). The only file I've changed is the sitemap.xmap to comment out the
SVG stuff (for now).
What else can I try? It has to be something simple at this point or a
conflicting pathname/library/jar with an existing app. *sigh*
Setup:
Cocoon 2.0.2
Tomcat 3.2.2 (with Apache)
JBoss 2.4.3
RedHat 7.1
IBM JDK 1.3.0

Then do rm -rf $TOMCAT_HOME/work and try again.
