Great idea, Paul. Following your idea, I also had to take the
following steps (posted here to leave an answer in the archives):
- use ${log4j.user.home} in my log4j.properties
- in my main() method, *very first* I obtain
System.getProperty("user.home") and .replace('\\', '/') in it, sending
the result to System.setProperty("log4j.user.home", ...)
- In my main-class, change the Logger definition from static final to
simply an object property. For me, I was able to do this without much
recourse because my main-class is effectively a singleton anyway. I
had to prevent log4j from initializing at class load of
MyMainClass.class (from the Logger declaration).
Thanks again,
