After following up the advice from David and others, I
think I've got the configuration I need. I'm posting
a minimal version of the setup as it seems to me that
this might be a fairly common requirement:
- I'm running two applications on a single server;
each has its own domain name.
- Within each application there may be one or more
contexts, corresponding to different versions of the
webapp (used by different customers).
- Various site-specific parameters need to be set
within the context, where they will override values in
web.xml.
- I don't want any kind of auto deployment
server.xml
----------
<Server port="8005" shutdown="SHUTDOWN">
<Service name="Catalina">
<Connector port="8080" />
<Engine name="Catalina" defaultHost="host1">
<!-- it seems that if both autoDeploy and
deployOnStartup are false, the host returns empty
pages, but if either one is false then it's OK -->
<Host name="host1" appBase="noapps"
autoDeploy="false" unpackWARs="false"
deployXML="false" />
<Host name="host2" appBase="noapps"
autoDeploy="false" unpackWARs="false"
deployXML="false" />
</Engine>
</Service>
</Server>
directory structure
-------------------
{catalina_home}
conf
Catalina
host1
ROOT.xml: <Context
docBase="${catalina.home}/ibo/ibo3" />
ibo4.xml: <Context
docBase="${catalina.home}/ibo/ibo4" />
...
host2
ROOT.xml: <Context
docBase="${catalina.home}/cbo/cbo.1.23.45" />
...
noapps
[nothing in here - would appBase="dev/null" work?]
ibo
ibo3
WEB-INF
ibo4
WEB-INF
cbo
cbo.1.23.45
WEB-INF
I seem to have problems if the context directories
aren't below ${catalina.home}, but this I can live
with.
Thanks to all who helped.
