Hi all, I need to clarify if I have understood logging separation correctly. I have almost the same scenario than described e.g. in this question: http://mailman.qos.ch/pipermail/logback-user/2010-March/001442.html. In my environment I have most of the application logic deployed to JBoss 7 as a JBoss module. Module have my shared libraries for common parts of the application as well as third party libraries (like Logback and Spring). My own custom shared implementations are using logging in a standard way by instantiating loggers as a static class variables. I am also having two war-applications which are using module described. Requirement is to have own logging context for each of the application. Which means applications should have their own log files, log levels and root loggers etc. I have tried to introduce JNDIBasedContextDiscriminator together with ShiftingAppender with no luck. My problem is that after my applications are initialized, it seems both of them is somehow sharing the same appenders. If I view status messages servlet, I can see that application B have initialized also RollingFileAppenders configured in application A's configuration file or other way round. RollingFileAppenders are wrapped inside SiftingAppender in both configuration files. Can anyone clarify to me can two applications using shared libraries have strictly separated configuration files which are introducing own loggers, appenders and logging levels? Or do I still have some kind of configuration problem with my setup? Thanks a lot, Ville
