Subject Re: Publishing without Restarting Tomcat

If you're working with standalone containers, I have no idea.

If you're working with containers behind web servers, here's what I know:

In the JServ days there was, with mod_jserv, a way to do a
"GRACEFUL_SHUTDOWN" (or something like that) of a particular container to
which mod_jserv was sending requests.  This would stop sending any new
sessions to that container, but would continue to send already-established
sessions there.  This would give you the functionality you're looking for. 
I know very little about using mod_jserv with Tomcat (as opposed to with
JServ) -- it's possible that this combination would give you what you want.

This particular feature is *not* supported by the load balancing system in
mod_jk, which is the current plugin of choice for the 3.x branch.  It is a
highly-requested feature, however, and there's been some discussion of it
here lately.  It's not impossible that it will get implemented within the
next month or two.
