Pretty simple - I was amazed.
First, go here: [link|http://www.galatea.com/flashguides/apache20-tomcat5-modjk-linux|http://www.galatea.c...mcat5-modjk-linux]
and follow the instructions for getting apache and tomcat working together.
Then have your "webfacing" author build a .war file. Uncompress the .war file in your webapps directory, edit your httpd.conf file adding the line JkMount lines:
JkMount /webfacingapp/ default
JkMount /webfacingapp/* default
Re-kick tomcat, re-kick apache and presto.
To answer my own questions, "No, you do not need to install jakarata-struts. No, there is nothing other than tomcat, apache and the connector required to make it go."
So, my webfacing app is running. That'll buy me some time while I really dig into tomcat.
