Subject Re: Geronimo readme for new app developers?

If you're trying to update only individual pages, you can copy them
into the config-store.  It isn't really a recommended approach, but it
should work well enough for development.  The recommended approach
would be to "redeploy" the application using the deploy tool (nearly
the same command except "redeploy" instead of "deploy" and run it on
the updated version of the WAR), or to copy a new version of the WAR
into the geronimo/deploy/ directory (if you deployed it in the first
place by copying the WAR there).

As for Tomcat and Jetty, in version 1.0, we're going to ship
Tomcat-only and Jetty-only builds to avoid this confusion.  So there's
only going to be one set of web listen ports and so on.  If you're
using M5 and you want to deploy an application for both Tomcat and
Jetty, you have to deploy it twice, and use Tomcat-specific and
Jetty-specific namespaces in your geronimo-web.xml file.  That's also
not really recommended, since we're trying to get away from the
two-simultaneous-container approach in 1.0.  In 1.0, you'll just pick
the distribution including Jetty or Tomcat (whichever you prefer) and
all your web apps will be deployed to that one.  As for whether you
should go with Jetty or Tomcat, they're really quite equivalent as far
as Geronimo is concerned.  Nearly anything you do with them will be
the same for either one.  The differences I can think of are:
 - the web access log is stored in different places
 - virtual hosts are configured differently
 - there are special configuration options for Tomcat valves

If you're just learning servlets and JSP, I'm not sure that stuff will
really matter, and the web container should be pretty transparent to
you.

Finally, my book is in the process of being update for 1.0 -- I think
I've made it through about 5 chapters so far.  :)  I'll keep the list
posted as there are significant updates.
