Is it possible to reference system environment variables (as opposed to Java system properties) in a log4j xml configuration file?

I\'d like to be able to do somethi

Answer 1

Create a system variable. I prefer to use setenv.bat for such variables.

@echo off
rem app specific log dir
set "APP_LOG_ROOTDIR=../app/app-log"
exit /b 0

Add reference in log4j.xml file
