[logback-user] Can logging configuration files be separated when using ContextJNDISelector?

[Ville Hägg]

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
