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.
