Problems running multiple instances in Tomcat
---------------------------------------------
Key: CONTINUUM-1963
URL: http://jira.codehaus.org/browse/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.
