Configuring log4j logging on Apache Tomcat

About this task

In these instructions, the following values should be replaced with values specific to your configuration. <<TOMCAT_HOME>> is the directory that Tomcat is installed in, sometimes referred to as CATALINA_HOME.

Procedure

If running Tomcat 6.x:

If you have not already done so, modify the <<TOMCAT_HOME>>/conf/catalina.properties file so that the shared classloader mechanism work the same as Tomcat 5.x.
To do this, verify that the entry beginning with shared.loader= reads shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar If running Tomcat 5.x or higher:

If running Tomcat 5.x or higher:

If it does not already exist, create a "shared/classes" directory under <<TOMCAT_HOME>>.
If it does not already exist, create a "shared/lib" directory under <<TOMCAT_HOME>>.
Copy log4j-###.jar into <<TOMCAT_HOME>>/shared/lib.
Note: Any specific version of log4j-###.jar should work. You can download the stable log4j version 1.2 installation from http://logging.apache.org/log4j/1.2/download.html
Copy a log4j.properties file into <<TOMCAT>>/shared/classes.

Example

To get a log file named "initiate.log" to show up in the <<TOMCAT_HOME>>/logs directory, an initial version of log4j.properties file is:

log4j.rootLogger=ERROR, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
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

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/initiate.log

log4j.appender.R.MaxFileSize=1000KB
log4j.appender.R.MaxBackupIndex=5

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{ABSOLUTE} 5-5p %c{2} - %m %n

log4j.logger.org.springframework=ERROR
log4j.logger.org.springframework.web.servlet.mvc=ERROR

#set to DEBUG to see hibernate and connection-pool logging output
log4j.logger.org.hibernate=ERROR
log4j.logger.org.apache.commons.dbcp=ERROR

#set to DEBUG to see Initiate-specific logging output
log4j.logger.com.initiatesystems=DEBUG

#set to DEBUG to set Initiate-specific verbose logging output
log4j.logger.verbose=ERROR
