Why did you expect it to work? Note that there is no way in pure Java of
accessing environment variables. Log4j is pure Java. This should tell
you that it's not going to work...

re: using system variables to init log4j

[Leif Hanack <le...@t-systems.de>]

you are right! maybe i descripted my problem wrong.

i want to initialize log4j using some properties that are
set on another place (through java).

i found some log4j-conf snipplets indicating me that it seems
to work (see below)


NOTE:
 # The presence of ${applicationRoot} in the logging configuration
 # is not a mistake. Internally the value of ${applicationRoot}
 # is set so that you can use it with standard log4j
 # properties to get logs to appear in your
 # webapp space.

rties?annotate=1.13)

my target was to get some info about the sentence "internally the value.."

nevertheless, thanks for your answer,
leif
