Subject: Re: Possible for G to directly consume a Tomcat server config w/o
	changes?

One quick way would be allow users to start a tomcat server from a
geronimo tomcat javaee5 assembly  or little G tomcat assembly(say
geronimo.sh start tomcatOnly=true).   It is possible to just launch
the tomcat server, and read the configuration files (conf/server.xml,
etc) and start a tomcat server from a geronimo tomcat assembly, by
using the Catalina.java provided by tomcat.   But this server/app
would have no relationship with geronimo, other than using the jars
provided by the geronimo tomcat assembly.   The deployed app would be
tracked only by tomcat, and not by geronimo.   We should be able to
achieve this without adding any new jars.

If we need more than that, I can for seen the following issues that
need investigation -
1. We'll have to provide better server integration with tomcat and be
able to read the server configuration from tomcat's server
configuration files, along with using config.xml configurations.
2. We'll have to migrate user's app automatically for the user, when
the user's app is a bit complicated that contains any need to require
a geronimo-web.xml
