Greg,

My company supplies a software system that is basically based on standard
servlets but since most of our potential customers do not own or want to own
a J2EE server environment we normally distribute our servlets packages with
a servlet container that can be simply embedded in a Java app (of no more
then a few lines). In short, people only install a JRE, unpack our ZIP and
fire up the app. For windows environments we cooked up a service wrapper EXE
and that is it.

Actually, our system consists of a central server that has no user
interfaces but handles XML requests through HTTP (servlets handle the
requests through the servlet container) which come from multiple application
servers (servlets that generate HTML as the UI and connect to the central
server via HTTP requests). Both tiers are servlet based and use the same
setup.

The embeddable server is Jetty (www.mortbay.org) which is one of the best
(free) servlet containers available and very simple to embed (including
sample code and great free support through the mailing lists).
