I want to deploy multiple applications in Tomcat. Each one will include Logback jars. I need to have the log configuration file external to the war so i can change them on the fly. Is the "best" way to do this to have an init servlet in each application which loads from the filesystem? I can pass a system property on Tomcat startup which points to a "config" directory.

Hello Nathaniel, You could include an external configuration file on a path dependent on the application. Example: -- contents of logback.xml shipping within myApp1, one of your web-apps <configuration scan="true"> <include file="/a/path/myApp1/logback.xml"/> </configuration> Auto scan feature is documented at http://logback.qos.ch/manual/configuration.html#autoScan -- contents of /a/path/myApp1/logback.xml <included> ... other content </included> File inclusion is documented at http://logback.qos.ch/manual/configuration.html#fileInclusion Note that logback will scan for changes in included files as well. HTH, -- QOS.ch, main sponsor of cal10n, logback and slf4j open source projects, is looking to hire talented software developers. For further details, see http://logback.qos.ch/job.html
