Setup Logging for Tomcat 6
I have downloaded "Apache-log4j-1.2.15.zip" from
http://tomcat.apache.org/tomcat-6.0-doc/logging.html, and began to following
some of the steps, and then I am left clueless on what to do following the
creation of the log4j.properties file, and copying "log4j-1.2.15.jar" in
/tomca/lib. Then it asks to "Place
output/extras/tomcat-juli-adapters.jarin $CATALINA_HOME/lib." I don't
know where "output/extras" is?
Any further guidance in this would be much MUCH appreciated.

Then why are you trying to change Tomcat's internal logging to use log4j? You can use log4j in your webapps with converting Tomcat itself to use it.

Does that require me to download the source files for Tomcat, and then
locate this Ant script? The instructions are very vague and assume the

Did you do step 3?
"Build the commons-logging additional component using the extras.xml Ant build script which is part of teh [sic] Tomcat source bundle."
It's created in the source tree after you run the specified ant script.

To put this more diplomatically (and considerably more words) :
The js-wrapper is an application written by other people, and has
nothing to do with Tomcat itself. It can, or cannot, be "doing things"
to intercept the standard Tomcat logging and send it somewhere else.
The people on this list answering Tomcat-related questions are not using
js-wrapper, so they do not know if it does do something to the logfiles
or not, and thus they cannot really help you.
The standard Tomcat packages for Windows, as downloaded from the Tomcat
website, do write logfiles, in the (tomcat_install_dir)/logs directory.
So they do logging "out-of-the-box".
Yours apparently does not, but the reason for that cannot be determined
as long as you are running Tomcat under control of js-wrapper.
You should first either ask the supplier of js-wrapper what they are
doing with the logs, or remove this Tomcat version, install a standard
one, and then come back here if you have more questions.
Understand, this does not mean that js-wrapper is not a good product. It
is just that it makes it difficult in this context to answer your questions.

If this is possible, it's not the default. But is it possible? If so,
what do I have to do to set it up to use the Windows Event Viewer?

The JS-Wrapper should have no effect on the built-in tomcat logging. It
(js-wrapper) can only log its self.

I don't know that js-wrapper, but if this is under Windows, might not

The phrase "spit out some logs" is pretty meaningless; what are you really trying to accomplish? By default, Tomcat's logs are in its logs directory, which usually contains several different log streams (e.g., catalina, host-manager, localhost, manager). You do not have to convert Tomcat to use log4j; it logs its own actions properly right out of the box.
If you want your webapp to log things, that has to be done in the code of the webapp.

All I want is for my Tomcat 6 to spit out some logs, and be default it's
not. Does not have to be log4j.xml if it does not have to be, but I was
under the assumption that logging changed for where we had to implement the
setup I posted in my original link.

Unless you really, really need to do that, don't. It's there primarily for people who can't (or won't) move to the new classloader structure when upgrading from older versions. Adding more classloaders to the hierarchy only slows things down.

Thanks for this clarification.

I didn't. I'm a Tomcat newbie. But I discovered the other day
that you can place libraries in the shared.loader by editing
"conf/catalina.properties".
I wondered why this wasn't stated more clearly in the
documentation for Tomcat 6. I only understood the issue
reading the documentation for Tomcat 5. The shared.loader
is still there in Tomcat 6, but not explained.
What's the rationale behind disabling it?
May we consider it deprecated?

I see. I wasn't aware of this property of the "common.loader".
Does the same hold true for the "shared.loader"?

Look at Tomcat's class loading hierarchy. Classes loaded from Tomcat's lib directory are shared at runtime by all webapps (and Tomcat, for that matter), whereas classes coming from a webapp's WEB-INF/lib or WEB-INF/classes are local to that webapp. If the classes from Tomcat's lib directory have any static fields or singleton objects, only one copy of those fields and objects exist for all the webapps.
I haven't looked inside log4j to see just what information in maintains in static fields or singletons, but keeping the log4j.jar with each webapp insures you won't get any unwarranted interaction in your webapps' logging.

"See the driver" - I think I used that expression yesterday. "Share a
logging complex" - could you expand a bit on what this means, or provide
a pointer to an informative document?
Thanks.

You really don't want to put the log4j.jar into Tomcat's lib directory unless you actually want all the webapps to *share* (not just "see") the same logging complex.

Re: Setup Logging for Tomcat 6
Posted by re...@yahoo.com.
To setup log4j, here's what I did.
Copy the log4j jar file to WEB-INF/lib. Put it in ${catalina.home}/lib if you want all webapps to be able to see this file.
Create a log4j.properties. Initially this file was in WEB-INF/classes/log4j.properties. Now I have the file in WEB-INF/lib/myjarfile.jar!log4j.properties (that is, at the root level of the jar file).
That's it, if I remember correctly.
When the properties file specifies a relative filename, it appears to be relative to ${catalina.home}, so specify for example "logs/myfile.log".
