I have been using commons-logging, log4j, Tomcat and Struts for a while now. When
configured it only gives the log messages I want and does not fill my screen or log
files with too much information. Without more information, my guess is that the
problem lies with your setup of log4j, not commons-logging.
Maybe a description of my own setup might help. I have two configuration files in my
class directory:
1. commons-logging.properties
Which contains a single line:
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JCategoryLog
2. log4j.properties
Which contains the follwing:
# log4j configuration file
log4j.debug=true
# Create two appenders, one called stdout and the other called rolling
log4j.logger.com.mypackage=INFO, stdout, rolling
log4j.logger.org.apache=WARN, stdout, rolling
# Configure the stout appender to go to the Console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# Configure the stdout appender to use the PatternLayout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
# Configure the rolling appender to be a RollingFileAppender
log4j.appender.rolling=org.apache.log4j.DailyRollingFileAppender
# Configure the name of the file for the rolling appender
log4j.appender.rolling.File=console.log
#Configure the layout pattern and conversion pattern for the rolling appender
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d{ABSOLUTE} - %p %c [%t] - %m%n
I use the standard call to get a logger in my code:
Log logger = LogFactory.getLog(MyClass.class.getName());
logger.warn("This is a warning");
If you are using Struts, you might also want to check that you have the correct jar
files. See http://jakarta.apache.org/builds/jakarta-struts/release/v1.1-b2/ and follow
the instructions for log4j users.

Subject: Totaly frustrated with commons-logging
Hi,
I'm totally frustrated with commons-logging. My applications uses log4j
and now tomcat switches log4j on because of commons-logging. Because I
do have to debug, I get a lot of absolutely unusable logs. The first log
of my application comes after 18000 lines of logging information.
Somebody might find that very cool I just find it terrible. I have read
the manual of commons-logging. I read about enterprise logging (find it
cool) but could not figure out how for example I could use the jdk-1.4
logging.
I really hate that commons-logging changes log4j that I get this huge
amount of unusable debug information.
How can I disable that?
Unfortunately it is not more possible to configure log4j that I just
want to see the logs of package xy. I mean a log4j configuration option:
log4j.rootCategory=DEBUG, A1, A2
log4j.logger.org.apache.commons=WARN
log4j.logger.org.apache.struts=WARN
log4j.logger.xy=DEBUG
