Where to store WAR application log files?

Question

I am trying to configure logging for my web application (WAR) in log4j.properties:

log4j.rootCategory=WARN, RF
log4j.appender.RF=org.apache.log4j.RollingFileAppender
log4j.appender.RF.File=???/my-app.log

Which file path should I specify for my-app.log? Where to save this file? I am currently deploying my application in Tomcat6, but who knows what will happen in the future. And who knows how exactly Tomcat will be configured / installed on another machine in the future.

Answer 1

What I finally did was:

• In continuous integration, settings.xmlI define a propertylog.dir
• In log4j.propertiesI define:log4j.appender.RF.File=${log.dir}/my-app.log
• Q pom.xmlI instruct Maven to filter .properties files

To save the configuration file, you can configure it as needed ... and even change it :)
