Getting nuts with log4j and Tomcat - real world example :(
Hi guys,
the following scenario:
I have configured Apache Tomcat logging with log4j. I've created 5
different appenders (each one for DEBUG, TRACE, INFO, ERROR and FATAL)
and assigned them to the root-logger
$catalina_home/common/classes/log4j.xml expecting the output of the
Tomcat basic classes going in there.
Now we have amongs others 2 servlets, some of the using the same
component which uses it's own logger - let's call it "CompassLogger".
Servlet 1 let's call it "IndexDOM", Servlet 2 let's call it "OccupationDOM".
For each Servlet I've created their very own appenders (again 5 for
DEBUG, TRACE, INFO, ERROR and FATAL) and their own logger, where I
linked to the appenders created above.
Example:
<logger name="OccupationLogger" additivity="false">
<appender-ref ref="OccupationDOMDailyFileAppenderInfo" />
<appender-ref ref="OccupationDOMDailyFileAppenderWarning" />
<appender-ref ref="OccupationDOMDailyFileAppenderError" />
<appender-ref ref="OccupationDOMDailyFileAppenderFatal" />
</logger>
No I also have to create the logger "CompassLogger" since the
component I'm using is instantiating this logger ("CompassLogger") in
both my servlets.
So I specified in each log4j.xml the appender for CompassLogger and
then linked within my CompassLogger to the appenders (did that for
IndexDOM and OccupationDOM).
Example:
<logger name="CompassLogger" additivity="false">
<level value="info" />
<appender-ref ref="CompassDailyFileAppenderInfo" />
<appender-ref ref="CompassDailyFileAppenderWarning" />
<appender-ref ref="CompassDailyFileAppenderError" />
<appender-ref ref="CompassDailyFileAppenderFatal" />
</logger>
My idea was, that every servlet is writing it's own DEBUG, TRACE,
INFO, ERROR and FATAL-files, and the conponent that makes use of the
CompassLogger writes to it's own log-file.
Unfortunaetely, that doesn't work.
IndexDOM writes it's own log-files as expected, however, OccupationDOM
always writes into the log-file that I've specified for Tomcat output.
I've got no more Idea how I should get this to work and I'm about to
create just one f*ck*ng BIG logfile, and kiss goodbye.
- Yes, I've asked in Tomcat maling-list, no answer by now.
- Yes, I've read the docs, maybe didn't udnerstand them properly
- Yes, I even browsed the *complete* log4j-manual available for money,
didn't find what I'm looking for
Attached I have my log4x.xml-files. I know it's a lot of code, and I
apologize for that, however, maybe it helps to understand the idea
behind it all.
Also, if you guys have some other suggestions how I can achieve, that
each servlet write it's own log-files, although accessing the same
component (jar-file) which calls "CompassLogger" (I do not have access
to the sources of that component).
If this post is too confusing, please let me know, I will then try to
put things in a more clearer way.

Posted by James Stauffer <st...@gmail.com>.
It appears that you want each "entry point" to be logged separately.
If that is correct you could:
1. Put the entry point (servlet name) in the MDC and use filters to
get the appenders to only log for the given entry point.
2. See if you create a separate repository for each servlet
