Look for references to the MDCFileAppender. Believe this is a 3rd party
solution. Don't recall where we found the source for this. We utilize
this appender to separate log files for each thread in several of our
applications. Couple of things we don't like about it, but it works
well enough.
I suspect with the new JAMonAppender you could do a pattern layout that only
has the thread in it, and then you would be able to create a buffer that
would allow you to display in a buffer from a web page the most recent N log
messages from each thread. You could also use this to write each log

JAMon looks like a pretty neat tool. Almost a full-fledged profiler...
I also noticed it has a lot of cross over with my program log4jdbc (see
http://log4jdbc.sourceforge.net)
actually JAmon does a lot more, but it is interesting to see some of your ideas
because I have some similar

Thank you for your reply and I really appreciate it.
May be The getRenderedMessage method in the
LoggingEvent is another place that I can intercept the
log message. But I'm just beginning to look how to

yeah, I'm actually thinking I am using too new a version of log4j for the
version of Tomcat (yes it is old) that I'm using.
As soon as I/we can, I will be upgrading to TC 5.5.
I also need to upgrade my ancient Eclipse version as well. Heck my whole
computer and servers are from a decade ago! :
Are there other logging subsystems that are capable of doing this other than
log4j? Is the only solution to:
tail -f main.log | grep [threadid]

This is starting to become the realm of the Tomcat support list. In any case,
you need to keep something in mind. The log4j.jar in common/lib is for
Tomcat's logging purposes. If you want to separate Tocmat logging from
application logging, also put log4j.jar in WEB-INF/lib and your applica
well, some progress.
I don't get an error, Tomcat doesn't post the INFO messages on startup like it
used to (with its logger class?)
Any way, I made this basic little servlet from their example, but it gives me
an error about the package.
import org.apache.log4j.Logger;
import org.apache.
I put the xml and properties file in the classes directory of my WEB-INF
folder, not the commons.
I guess I did that incorrectly. Let me try that again, and move them to that
directory.
Thanks, Jake!

my logging seems to work fine, for the most part, with Tomcat's built in

My commons-logging.jar file is in the following dir:

My commons-logging-api.jar is indeed in the commons\lib class.

Use the syntax ${xxx} in your configuration file, replacing xxx with the

The purpose of Renderers is to generate a String representation of an
Object. Since a String is already a String, there's no need to do any
additional rendering.
The getRenderedMessage method in the LoggingEvent is what is responsible
for calling any defined renderers. This method has
ok, thanks for that extra advice.
this is the title of the jar file I downloaded.
log4j-1.2.14.jar
Any way, I'm going to reunzip the directory into my app. I first just extracted
it to the root of the hard drive, rather than to the app in Tomcat itself.
I'll redo that and go from there, too.
Is it possible to configure the output file of a file appender using the
environment variable APPDATA (Windows XP)? What is the syntax in the
log4j.properties file and do I have to send an argument to the JVM?
Thanks,
