Re: Help with Log4j

[Eric Bloch]

I eventually made this work in tomcat 5.0.24 and wasted lots of time on 
it, too.  The @#&*(! commons-logging combined with the fact that tomcat 
uses it itself, makes for all sorts of possible problems.  It seems to 
me all commons-logging really is .... is a class-loader that breaks 
inside servlet containers in different ways depending on how the 
container does its own class loading and how the container uses or 
doesn't use commons-logging itself.

The trick for me was to add commons-logging.jar (impl not api jar) and 
log4j-1.2.x.jar to $TOMCAT_HOME/common/lib .  I also made sure that the 
version of commons-logging.jar that I added to $TOMCAT_HOME/common/lib 
matched the version of the commons-logging-api.jar in $TOMCAT_HOME/bin

Good luck!

Hi,
 
I'm having trouble getting log4j to work in conjunction with commons 
logging, Axis 1.0 and Tomcat 5.0.19.  I've tried altering the 
log4j.properties in the axis.jar file, adding the log4j jar file to the 
tomcat shared\lib, common\lib and server\lib directories, adding 
log4j.properties files in the tomcat shared\classes, common\classes, 
server\classes and the axis\WEB-INF\classes directories, all to no avail.
 
I've googled on this with all combinations of tomcat, axis and log4j 
that I can think of, but I just can't seem to coax anything other than 
the INFO level debugging into the tomcat\logs\stdout.log file that I had 
upon first installation of tomcat. 
 
I'm using the LogFactory.getLog() method from commons logging, which 
should choose log4j if possible.  However, when I output the Log object 
that is returned, it's an org.apache.commons.logging.impl.Jdk14Logger.
 
I've been banging my head against this one for three days now - has 
anyone out there managed to get this combination working?   Any and all 
tips gratefully received.
