Re: how can i configure Tomcat's log4j to log in a separate file for each webapp?
Hello dB;
This is the step by step actions to configure your log4j logging in one place in Tomcat "lib/log4j.properties"
Actions
---------------------
1- Remove logging.properties from conf/logging.properties
2- Remove tomcat-juli.jar from bin/tomcat-juli.jar
3- Get "tomcat-juli.jar" and "tomcat-juli-adapters.jar" from "http://godel.cs.bilgi.edu.tr/apache/tomcat/tomcat-6/v6.0.26/bin/extras/" or any other place
4- Put "tomcat-juli.jar" to "bin" folder
5- Put "tomcat-juli-adapters.jar" to "lib" folder
6- Download "log4j.jar" and put to "lib" folder
7- Creates a log4j.properties and put it into "lib" folder.
Example Configuration:
log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.base}/logs/tomcat.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
//Manager application
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager]= DEBUG,B
log4j.appender.B=org.apache.log4j.RollingFileAppender
log4j.appender.B.File=${catalina.base}/logs/gurkan.log --> Its own log file
log4j.appender.B.MaxFileSize=10MB
log4j.appender.B.MaxBackupIndex=10
log4j.appender.B.layout=org.apache.log4j.PatternLayout
log4j.appender.B.layout.ConversionPattern=%p %t %c - %m%n
//Example application
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/examples]= DEBUG,C
log4j.appender.C=org.apache.log4j.RollingFileAppender
log4j.appender.C.File=${catalina.base}/logs/example.log --> Its own
log file
log4j.appender.C.MaxFileSize=10MB
log4j.appender.C.MaxBackupIndex=10
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern=%p %t %c - %m%n
This will creates a root logger --> INFO and logs message to tomcat.log.
Each web application can override ROOT like I did for manager and examples web applications.
I hope it helps :)))

I have a lot of web apps and developers that stand on their head for logging. My customers end up finding logs all over the place and enforcing it by convention is getting harder and harder. I'd like to configure logging for them rather than leave logging to their discretion. So I want the centralized log4j configuration that can insert the web app name into the file name that belongs to the tomcat installation.

I do this all the time.
For applications using commons-logging, I place commons-logging.jar
and log4j.jar in the webapp's WEB-INF/lib directory and
log4j.properties in WEB-INF/classes. The same works if slf4j-api and
slf4j-log4j12 is used instead of or in addition to commons-logging.
I never add jar files used by individual webapps to tomcat's lib or
any other directory shared by several webapps.
kind regards

Posted by "dB." <db...@dblock.org>.
And can I do this for an application I don't know anything about? I mean all I really want is
log4j.appender.R.File=${catalina.base}/logs/${APPLICATION.NAME}.log
