Seperate log files for Tomcat / Java errors and application info

[Robert Bowen]

I have been scouring the list and have found a few mentions of how to maintain 
two seperate log files but I can't find examples and in any case what I would 
like to do is something a little different although I'm sure easy to do.

My app spits out all kinds of info in a certain, precise format. Tomcat 
startup/shutdown and Java exceptions are sneaking into my log. I would like 
tobe able to have all non-app messages go to one log, and app messages to 
another.

I am using xml format andmy log4j.xml is dirt simple. Can anyone tell me how to 
do this, or point me to a link? The documentation is enormous and they seem to 
explain just about everything you can possibly do with log4j ... except what I 
want to do. :(

Thanks in advance, log4j.xml follows,
Bob
