Subject generic deployment question
Date Thu, 16 Feb 2012 21:12:01 GMT
Assume latest Tomcat 6.x for current deployment, and 7.x for future deployments.

I host an app for a couple of dozen customers.  Naturally, upgrade time can be a bit of a
pain, and I'd like to simplify things.
Assuming that all the customer-specific information (DB connection info, logger info, etc.)
can be described as resources in the context.xml file, would it be possible to put the actual
webapp in a single pre-exploded directory without causing Tomcat fits?

Example directory tree:

  WEB-INF  (with generic web.xml for web-app-1.1)

<?xml version="1.0" encoding="UTF-8"?>
<Context path=""
  <Valve className="org.apache.catalina.authenticator.SSLAuthenticator"
        securePagesWithPragma="false" />
  <....resources definitions.... />

Then when a new release comes out, I can deploy the web-app once and modify the individual
customer's contexts to point to the new release path as they choose upgrade (or all at once).

And, yes, I know that disk is cheap and I could just do it by replacing 3-4 dozen war files
nearly as easily.  And right now, I'm not sure if the future 7.x versioning feature will come
in handy as our dev staff haven't started investigating 7.x yet.
