Subject [jira] Created: (CONTINUUM-1963) Problems running multiple instances in Tomcat

Problems running multiple instances in Tomcat

                 Key: CONTINUUM-1963
             Project: Continuum
          Issue Type: Bug
          Components: Core system
    Affects Versions: 1.2
         Environment: Continuum 1.2.2 web archive (not standalone)
Tomcat 6.0.18
            Reporter: Michael Johns

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.
