Thanks Jake -- My /etc/tomcat6/catalina.properties:
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar
That works too
--but I'm unable to see where ${catalina.base} and ${catalina.home} are
defined. That isn't so immediately relevant though.
These can be set in your environment as the following OS system properties....
CATALINA_BASE
CATALINA_HOME
The Tomcat scripts pick these up and uses them to set the following Java
system properties....
catalina.base
catalina.home
The scripts will use defaults if you don't provide them. And catalina.base
will be set to the value of catalina.home if not not explicitly set to
something else.
At this point I have no preference as to whether the logging is server or
app. I just want *something* --and I had that *something* with tomcat5
without too much trouble.
But what that "something" is is an important question which you have yet to
answer. Do you want to see logging from your own application or from Tomcat?
What you have set up so far is sufficient for the former, but not the latter.
Keep in mind, this is *not* a Log4j question, but a Tomcat question. From
Log4j standpoint, auto-configuration is working. I will give you a bit
further advice here, but if you want more you need to re-read the introduction
of the Tomcat Logging page, not just the Log4j specific instructions and/or
contact the Tomcat user list.
What's most important to me is that I can see
something running through syslog.
"syslog" seems to imply you want Tomcat logging. If you read a bit more
closely, you'll understand why you see no logging from Tomcat.
Specifically....
[begin quote]
By default, only java.util.logging is available for the logs generated by
the Tomcat internal loggers, as Tomcat uses a package renamed
commons
logging implementation which is hardcoded to use
java.util.logging. Use of
alternative logging frameworks requires building or downloading
the
extras
components which include a full
commons-logging implementation. Instructions for configuring the
extras
components to enable log4j to be used for Tomcat's internal
logging may be
found below.
[end quote]
This isn't working for me:
> /usr/share/tomcat6/lib/log4j.jar
> /usr/share/tomcat6/lib/log4j.properties
Actually, it is, from Log4j's perspective. The logger repository is getting
auto-configured using the log4j.properties you provided. That you see no
Tomcat logging is because you have not yet followed the instructions below.
...and I wonder if these instructions are why. If these instructions require
precise applicaton then what do these instructions mean?
You are going to have to be more precise about what exactly you don't
understand about these instructions. If you follow them, you will see Tomcat
logging through Log4j. I've done it and I know it works. If you find these
instructions a pain in the [you know what], I don't blame you. But the cause
of the pain has nothing to do with Log4j and everything to do with Tomcat. If
you have complaints, I encourage you to send them to the Tomcat team.

Jacob Kjome said the following on 7/15/10 10:40 AM:
Tomcat's catalina.properties contains...
common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar
This means that, assuming that "/usr/share/tomcat6" is the path set for
${catalina.home}, the following should work fine...
/usr/share/tomcat6/lib/log4j.jar
/usr/share/tomcat6/lib/log4j.properties
That said, is you purpose application logging or server logging (or both)?
For application logging, this should be fine, though you'll share a
logger repository with all apps under Tomcat (unless you include
log4j.jar in WEB-INF/lib and log4j.properties or log4j.xml in
WEB-INF/classes ....or you use a logger repository selector).
For server logging, you need to following the instructions you already
referenced....

I was able to get log4j working with syslog without too much trouble
using tomcat5. Yet with tomcat6 I'm having a heck of a time trying to
figure out where log4j.properties should go.
tomcat5:
JAVA_OPTS="$JAVA_OPTS
-Dcatalina.ext.dirs=$CATALINA_HOME/shared/lib:$CATALINA_HOME/common/lib"
/var/lib/tomcat5/common/lib/log4j.jar

These instructions are over 8 years old so I imagine this section, in
particular has changed quite a bit "Default Initialization under Tomcat"

And lastly, there's this snippet on the Apache website -- is all this
necessary?
