Newbie question

[Salou Loic <lo...@gva.eri.ch>]

Does anyone knows how I can specify dynamically the name of the file ? I
sort of would like the following
- Let Log4j use a property in my config file, likely
"log4j.appender.XXX.filePath=T:\\LOG"
- specify dynamically in my java classes wich filename to use. The reason is
that I am currently developping an application logging messages in files
situated in a shared folder, and I need to give a unique name for each file
(currently I chose to get the client machine name, which is unique)

I can (it already works) subclass RollingFileAppender (or others) and change
the setFile methods, but I would prefer a lot not to override Log4j
behaviors to avoid future diffulties in evoluating with Log4j.

But in the existing parameters I couldn't find anything but the
"log4j.appender.XXX.File=T:\\LOG\\LOGFILE.LOG"...

Please help me !
Thanks

Not sure I have understood your problem exactly, but you could use 
environment substitution in your properties/xml file.

log4j.appender.XXX.filePath=T:\\LOG\${client_machine}.log


${client.machine} would need to have been set in the system properties 
before hand.
