[logback-user] How to know the filename used by the appender of a given logger

[Ulrich]

Thank you. I don't want to set the filename or maintain the appender 
from my program. This is up to the operators running the application. 
And I don't want to add limitations beyond those given by logback 
itself. I thought logback would know the file it uses - why not supply 
the name?
I could also (and I do it already) set the logfile by the operationg 
system and provide the name as an argument. In this case the I must 
request that only the console-appender can be used. But I don't like 
this approach.
