I don't anymore. I am pretty new to log4j and started a new project where I
figured it would be nice to be able to have data logged to different tables
based on who the client was. Not the best way to do it, but I was wondering
if there was a way to do this. Now thinking about it, probably not what
log4j is used for. To do this I would probably have to reload the log4j
config file for each thread (and not sure if that would cause threading
issues).
I did figure out how to load parameters into the log4j thanks to all the
help from everyone. I will be setting up java's System properties, and then
reloading the config file once.
Thanks for all the help
