Subject RE: [Logging] Where to put new jars in Tomcat?

It just sounds like it is not finding that file. If the new
commons-logging in your server\lib is using log4j, maybe you need a file in server\classes.

Subject: [Logging] Where to put new jars in Tomcat?

I have downloaded commons-logging-1.0.3 and found two jar files in it:

Now which one am i supposed to put in my webapp/WEB-INF/lib and what about
tomcat's server/lib and common/lib? I found that tomcat's server/lib already
had commons-logging.jar and I replaced it with the new one having the same
name. Also replaced the existing common/lib/commons-logging-api.jar with the
new commons-logging-api.jar. But when tomcat starts up i get:
log4j:WARN No appenders could be found for logger
log4j:WARN Please initialize the log4j system properly.
Do I have to put log4j in tomcat too? I have log4j.jar in my WEB-INF/lib. I
also have and and

Right now I am not getting any log messages anywhere.

Any where i can find exact steps to make this work? i have searched the
archive and tried some of the combinations nothing seems to fit in.

I am using Tomcat 4.1.18 on Win2000 and JDK1.4.
