Make sure your initial context factory implementation is in WEB-INF/lib,

Howdy,
Yes. Instead of them sharing log4j.jar, put a copy of the jar in each
app's WEB-INF/lib folder. Then keep the separate config files as you've
done, in each app's WEB-INF/classes folder. Make sure there's no
log4j.jar in tomcat's common/lib directory.

Howdy,
I'm a fan of the Level system and its relationship, so no I'm not
interested in your suggested mods, but I wanted to throw out an idea or
two for you that might reduce the need for coding:
- Can you use separate logger repositories as your types ?
- Can you use a Filter attached to the
that are calling them?
If this is a problem, then is there a way around it?
It seems like I want some type of logging context that I can
establish
on
a thread that defines ALL of the log settings, not just a name.

Howdy,
U, so basically then it is not possible to define a directory path
in
the log4j.xml properties file so that log files are placed relative to
the
web apps root directory? Or for that matter relative to any known
anchor
point like the server root directory?
A problem we have is that
will be glad to be convinced otherwise by a benchmark, however...

Thanks, thats a help but because of the setup of our application, I

use the first two options, and I'd rather not define another properties

No. It would be

Howdy,
What should happen if the configureAndWatch() function is called twice?
Are the previous settings erased? Are they accumulated ?
It wouldn't be that hard to simply test this and see what happens ;)
But looking at the code, you see:
- configureAndWatch always creates a new XMLWatchdog,
Howdy,
I would really want this sort of feature benchmarked for memory use ;) Perhaps this
is one of the reasons log4j has better performance than your current java trace kit ;)

Howdy,
this may be more a tomcat question so appologies if it is off-topic.
I want to plcae the log file under %TOMCAT_HOME%\logs (where all the
tomcat logs go).
Reading the archives of this list or the tomcat-user list would've
revealed answers, as this is a fairly common question.
