Jason,
Thanks for the tip.
I ended up also finding a solution that will meet my needs. Apparently,
you may create a configuration file in the webapps folder that contains
fragments from the server.xml file. The configuration file needs to be
named according to the application context that you are intending to
configure. Example: mywebapp.xml could contain configuration fragments
for the /mywebapp context. The snippet shown below will create a new
filelogger for the /mywebapp context:

Subject: Re: Creating Loggers at Deployment Time
Patrick,
I have done this using a the Java logging API in conjunction with a
context listener. When your application loads, you have the context
listener configure the logger to do the output you want. In my case I
create a log in the $CATALINA_HOME/logs directory named after the app
and do standard revolving logfiles. I also set the default logging
level here.
The nice thing about the logging api is that it is hierarchical and so
once you have configured the root logger, additional loggers (one per
class in my case) can be set as children to the root. All the children
will use the properties of the root (like the log file you defined) as
well as have their own properties which you can adjust to suit your
debugging situation. Using this approach allows you to set the
debugging level of a class higher if you are working on it and it
leaves the other classes in a 'quiet' mode.
One of the things I really like about the java logging API is that it
allows you to change the loggin level at runtime. In my application I
will be adding a management interface that will allow changing the
debug level of a specific class on a deployed application at runtime.
