You can configure your entire logging system via a single config file. You
are not limited to one logger/appender per config file. Besides, children of
the the logger inherit from the parent, by default, so when you configure a
given logger, e.g., the root logger, that same config applies to all children
(unless you set additivity to false at some point in the hierarchy). I assure
you, there is no need for multiple config files.
The manual [1] shows examples of properties config files. The wiki [2]
provides examples of XML config files. And any search engine will provide
lots of extra resources showing how to write Log4j config files. Please read
these resources and take a crack at the config. Feel free to post your config
if you have more questions.

Well been doing that already.
Lets start with the basics
What is the syntax for configuring multiple loggers using an xml file?
If I use log4j.xml or log4j.properties I can configure one logger with code
straight from a tutorial...
org.apache.log4j.Logger conLogger =
Logger.getLogger(BaseConfig.class);
Using this as a model I would think I would want
org.apache.log4j.Logger qryLogger =
Logger.getLogger(BaseConfig.class);
org.apache.log4j.Logger lgLogger =
Logger.getLogger(BaseConfig.class);
org.apache.log4j.Logger exLogger =
Logger.getLogger(BaseConfig.class);
Yet if I use this construct, even if I set loggers in the xml file, the last
defined file will write console output to its log.
So it seems to me that instead of basing a logger on a class, I need to base
a
logger on a unique xml file.
I can use
URL url = Loader.getResource("conLogger.xml");
DOMConfigurator.configure(url);
again from the same tutorial.. but it only works with 1 xml file.
So if I am limited to 1 xml file how do I configure separate loggers and
appenders in 1 xml file or is there a way I can have 4 separate xml files
with a
unique logger and appender for each?

I suggest that you take a crack at the configuration yourself. If you still
have questions, post it and we can help you tweak it.

Greetings
I tried searching for this on the mail archives link, the link seems to be
changed.
My goal:
I have 4 files for logging. ConLogger -> logs to console, lgLogger -> logs
to a
log file, qryLogger that logs to a log file, delLogger that logs to a log
file,
and exLogger that logs to a log file
lgLogger logs generall aplication activity. I have used addAppender to
ensure
everything logged to the console is also logged to lgLogger
qryLogger logs nothing but query information
exLogger logs all exception errors
All 4 of these files can support debug thru fatal entries.
I have used this same pattern in several "batch" type jobs for about 4 years
now.
These files are configured in the primary java class.
What I want to do is change the configuration from "hard" coding these log
files in the app to using xml files for configuration.
The problem I am running into is it seems when using xml or property files
log4j makes the assumption of only one logger with multiple appenders per xml
file. I want or think I want 4 distinct loggers with each having a separate
appender.
Is this correct? Has anyone else tried to do something similar with log4j?
Any
idea on how to achieve this?
Thanks!
