Thanks! How will different contexts be invoked depending on the URL?
Well, maybe I misunderstood the original question :-)
My presumption was that the same code exists at, say,
http://dev.example.com/ and http://www.example.com
which are clearly different Contexts, even if they're on the same
machine being run as virtual hosts.
So each Context has a Resource addressing the appropriate DB.
Also, I need to distinguish between the test and production environment
in the code to figure out whether emails should be sent or not. Can I
detect the current context there?
If your setup is as described above, you could use getServerName();
alternatively, put a Parameter in the Context to turn on/off email
sending.
Apologies if this isn't relevant to your environment, though!

RE: Different JDBC sources?
Hi, Yes it's called source control and build management. The "same", as you call it, code is the managed master code (cvs/vss etc.) and when you want that pushed to different servers you do so with automated build scripts like Ant, or deployment using application server deploy tools. The point is that you don't modify you code in-situ within the staging/production Tomcat server, you do it in the local dev envionrment, and when ready for deploy, it gets committed, tagged and then war'd up and deployed. Sounds like this may just be too much for your project, but it's nevertheless the standard way.

Re: Different JDBC sources?
Simon, As a relative Tomcat newbie, I can't find anything about how to use two different JDBC sources with the same codebase. I'd like to have two different URLs that use the same classes and JSP pages, but reference two different databases (test and production). Is there a standard way of achieving this? Shamelessly promoting our own product, you might want to take a look at Qilan. An OS X application, Qilan accesses multiple JDBC database sources and automatically creates all the necessary JSP code. The developer merely creates web pages (webtemplates), with or without specialized tags, then exports them to Tomcat/webapps. If you are using SQL, Qilan handles this as well.

Different JDBC sources?
Hi, As a relative Tomcat newbie, I can't find anything about how to use two different JDBC sources with the same codebase. I'd like to have two different URLs that use the same classes and JSP pages, but reference two different databases (test and production). Is there a standard way of achieving this?
