Michael Johns commented on CONTINUUM-1963:
------------------------------------------

One more thing is the location of continuum.log.  That's currently configured in WEB-INF/classes/log4j.xml.  Without a change, all instances log to the same file, which gets very confusing.

> I'm trying to run multiple instances of apache-continuum-1.2.2.war in a single Tomcat container.  I've got it up and running just fine, but there are a few areas where the instances overlap that prevent me from actually using them.
> 1. By default, the values from the "Configuration" page on the GUI are saved to continuum.xml in the ${appserver.base}/conf directory.  This is a problem because all instances want to share that same file.  That means all instances try to share working directories, which is very bad.  I tracked down this value in the WEB-INF/classes/META-INF/continuum directory of the web archive, but changing it there did no good.  Then I found it in the spring-context.xml file within the META-INF directory of the continuum-configuration-1.2.2.jar file that's within the WEB-INF/lib directory of the main web application.  Updating it in that file did the trick.  But now I need a separate web archive for each of my instances, which is what I was trying to avoid in the first place.
> 2. The values on the "Appearance" page are saved in a continuum-appearance.xml file that also lives in the ${appserver.base}/conf directory.  Unfortunately, the path to this file is hard-coded in the DefaultAppareanceConfiguration implementation.  The location of this config file should really come out of config as well.  Fortunately I don't care too much if each of my instances has the same footer.
> There needs to be a way to override the default configuration directory per instance without having to dig two libraries deep into the web archive.  As far as I can tell, this is the only thing preventing me from cleanly running N Continuum instances in parallel.
