Log4j loads "log4j.properties" from the classpath of the classloader that
loaded itself(log4j classes). In your case, log4j is loaded by tomcat
classloader, since it is present in $TOMCAT_HOME/lib. Classes and files
under WEB-INF/classes are not visible to that classloader, hence the
problem.

Dear All:
I'm running tomcat 6.0.7 beta on a linux redhat 8 system. Here are my
questions:
1. I tried to set up some useful libraries in directories outside
$tomcat_home/lib but they were not recognized.
I did that by setting:
CLASSPATH=/srv/lib/hibernate-
3.2.1.GA:/srv/lib/hibernate-tools-3.2.0.beta8:/srv/lib/j2ee-1.4:/srv/lib/misc:/srv/lib/struts-1.3.5
export CLASSPATH
and restarting tomcat, but it didn't find my libraries. So I put them
all under $tomcat_home/lib. Is that right?
2. I deployed a web application called "Catalog" to tomcat (it uses
Struts 1.3.5 and Hibernate 3.2.1 GA), and placed log4.properties under
webapps/Catalog/WEB-INF/classes. It is not recognized, and I get these
warnings:
log4j:WARN No appenders could be found for logger
(net.ruready.struts.filter.FindItemFilter).
log4j:WARN Please initialize the log4j system properly.
Also, I don't see any output although my log4j is configured to output
messages. On my windows XP system,
I see messages and I can declare libraries outside tomcat, but I'm using
MyEclipse 5.1 so I don't know how it's done
behind the scenes.
3. When I run my app, it hangs trying to access the database. I have a
hibernate.cfg.xml which works on windows, but once again,
I am not sure what is going on because I don't see any log messages on
linux.
What am I doing wrong, and how should I configure tomcat and my web app?
Attached below please find my relevant config files.
Thanks so much in advance,
Oren
