Howdy,
There is no magic token for the app name in the DefaultContext element.
So you need a Logger for each Context explicitly defined. The Logger
for a Context handles all servlets for that context. If you have one
logger in your DefaultContext and no other Contexts defined, all output
from all your contexts will go to this one logger.

The above applies to tomcat 4 and 5.

I would not go down this route at all: instead, use a real logging
system like log4j.
