This change (which is pretty importantant in an "enterprise" style environment) never got into the code base: $ svn diff Index: logback-access/src/main/java/ch/qos/logback/access/tomcat/LogbackValve.java =================================================================== --- logback-access/src/main/java/ch/qos/logback/access/tomcat/LogbackValve.java (revision 1509) +++ logback-access/src/main/java/ch/qos/logback/access/tomcat/LogbackValve.java (working copy) @@ -103,7 +103,7 @@ public void start() { if (filename == null) { - String tomcatHomeProperty = System.getProperty("catalina.home"); + String tomcatHomeProperty = System.getProperty("catalina.base"); filename = tomcatHomeProperty + File.separatorChar + DEFAULT_CONFIG_FILE; I also can't find the post regarding bootstrapping tomcat with logback intercepting all logging - did that ever get through? I've been running that way for some time and have not seen any problems. The resulting control, consolidation and archiving of logs is fantastic! - mike -- View this message in context: http://www.nabble.com/Using-logback-in-tomcat-tf2890321.html#a10035474 Sent from the Logback User mailing list archive at Nabble.com.
