I've got a web application that runs succesfully on Win/Tomcat 5.0 and
on RH/resin 2.x. I am pretty sure my problem is with the container
configuration. I need to run several versions of the app and I'd like
to do this using several different Tomcat instances, with different
$CATALINA_BASE directories. (There is an Apache front-end but that
isn't relevant yet.)
I cannot seem to get the app to start. I have a directory set up as the
CATALINA_BASE with the following content (I've left out a couple
unrelated dirs for simplicity):
base_dir
apps
myWebAppBaseDir (which contains WEB-INF and so forth)
conf
Catalina
localhost
ROOT.xml
context.xml (the default that comes with Tomcat)
server.xml
web.xml (the default that comes with Tomcat)
(other default files: catalina.properties, tomcat-users.xml, etc)
logs
temp
webapps (empty)
work
I believe the necessary configuration is only in the server.xml and the
ROOT.xml files, and the rest are OK to use the defaults. I've pasted
the server.xml and ROOT.xml files below for reference. As you'll
notice, I am attempting to run the app from a directory structure, not
from a WAR file, and it is intended to run as the root application with
no context path.
Using the configuration I've currently got (below), I can start Tomcat
and no errors show up in the logs, although the startup process my app
normally goes through does not seem to occur (that is, the messages from
it don't show up). If I try to hit a page on the server, I get an
exception (below) that I can't find anywhere on Google nor in this
list's archives.
I tried configuring the app by placing the content of ROOT.xml into the
<host> element of server.xml, as is recommended AGAINST in the Tomcat
docs. This produced the same exception.
In all cases I start Tomcat using a script I wrote that sets JAVA_HOME
and CATALINA_BASE and then calls CATALINA_HOME/bin/catalina.sh (full
script below).
Any ideas on what to do, or pointers to further research, are much
appreciated!
Thanks,
Rachel McConnell
