Re: best practice question: webapp relative filenames in FileAppenders

[Jacob Kjome]

Why not use a system property and reference it in your config using the 
usual ${someproperty} syntax.  For instance...

${catalina.home}/logs/mylog.log
If you want it to be dynamic per webapp, then you can set the system 
property in a servlet context listener and then perform the manual 
configuration of Log4j.

And if you are configuring manually via a startup servlet, why put 
log4j.properties in the classpath?  It would get picked up there 
automatically anyway (at least under a server using child-first 
classloading behavior recommended by the servlet spec) assuming log4j.jar 
is also in WEB-INF/lib.
