OK, maybe I'm being dense and it will all flash for me in a minute,
but it seems like this new feature, while better for an all-Guice, all-
servlet system does not satisfy the same use cases as before.
My web.xml file can't be empty of servlet definitions, because I don't
control the entire file. I have a couple of servlets that are the
entry point to the fairly self-contained org.restlet world that uses
Guice extensively, but there's plenty of other stuff in web.xml
(legacy to me, important to others) that will never be in the Guice
club and will always use servlets. (And note that the servlets I have
are just glue to the web.xml world, and I'd rather live without them,
so the ServletModule for Guice is just a piece of glue code to me.)
So I can just put in new ServletModule(){serve("/shoppingcart")...} in
my code, and it will all work as long as nobody uses /shoppingcart in
web.xml?
Thanks to you and Jesse for taking the time to explain this (and other
stuff in the past) to me.
