daemon threads left a program will exit.
as such, it executes in the same jvm instance as it's parent.

Hi,
1. The original question was if there is some highly tomcat-specific
code
that enables a reboot at runtime. Spending very little time going
through
the source code of catalina, it seems to me that even highly tomcat-

This is true, which is

What's running your program (in order to wait and issue a startup

The listener would be started outside of the container, in a separate

It just hit me --
what about a (protected) servlet that spawns a daemon thread, which in
turn calls Runtime.exec( tomcat stop / start script)?
Admittedly, I'm hazy on my Java threading right now, but if that would
work then it's something that's completley within the container, and no

Wouldn't it be possible to restart tomcat by writing a server-side
program to trigger a shell-script?? Of course that may disrupt the
operation of the website itself - I'd have to consult the docs to be
clearer on that.

If you're looking for a full restart, there are several ways (in varying
levels of hackishness).
