That's a good sign. It means Log4j is being used. Have you put log4j.xml or
log4j.properties in common/classes? Make sure you define a root logger with
an appender. I would set the level to something like "warn" so you don't get
any debug or info messages from arbitrary loggers by default.

also, Jake,
my commons-logging.jar file (NOT my commons-logging-api.jar, but just
commons-logging.jar) is in the following dir. for me:
$TOMCAT_HOME\server\lib
should I throw in the log4j jar file in there as well?
Both need to be, specifically, in common/lib and the Log4j config file has
to
be in common/classes. But, again, I don't recall how this works with
Tomcat4
which is what I presume you are using based on your use of Tomcat's
FileLogger.

ok, I did check out the wizard site, and that's a big help..thanks.
I really like that.
While I've put the properties, xml and jar file all in the WEB-INF/lib
directory of my app, I still have a problem.
If I change the server.xml reference in the following tag from
org.apache.catalina.logger.FileLogger to org.apache.log4j.Logger,
Tomcat balks upon startup.
I'll keep messing with it...I'll get there.
Are you using Log4j for application logging or Server logging? These are
two
very different beasts, expecially with the old version of Tomcat you must be
using, since you are using FileLogger. I would guess it is 4.0 or something
very old like that.
For Application logging, you don't mess with Tomcat's logging at all. For
server logging, piping it through Log4j may or may not be possible with
Tomcat
4.xx. It certainly is with 5.0+ by going through commons-logging. Also, to
configure Log4j for Tomcat, log4j.properties or log4j.xml would have to be
in
commons/classes along with log4j.jar and commons-logging.jar in common/lib.
Don't mess with this. You've got enough on your plate with figuring out the
basic workings of Log4j. Concentrate on using Log4j for logging in your
application only for now.

I'd looked at the Log4j on Apache's site...are we talking about the same
thing?
The links have "apache" in them. Yes, Log4j is part of the Apache Logging
Project...

Yes, I had put the jar file in there, and just now added the properties file
as well. However, I don't find a log4j.xml file anywhere. The only place I
find one is in my Eclipse folder workspace, referencing a download I made of
Quartz sometime ago. THAT log4j.xml file wouldn't work, I don't think would
it?
Well, maybe. How would I know? You haven't shown it to me. In any case,
again, this is an issue of education. One thing that can help you with
config
files are the available wizards at WizardForge...

Ok, I'll see if I can find some valid tutorial, because the one I read in
that link I included in this post was woefully outdated and inadequate, and
further, emailing that guy who authored equally proved fruitless, as it
bounced back and he no longer monitors it.
Have you looked at the Log4j web site itself or the Log4j Wiki? There are
lots of resources besided the link you posted...
