Re: How to tell if ClassServer is running

It's the ClassServer that comes with the River release and it is started
with the start.jar utility.  I figured out how to see if one is up, but
the shutdown is still problematic.  It is apparently not
Administratable.  The documentation speaks vaguely of a -stop parameter,
but the source code documentation says...

* If the <code>-stoppable</code> option is given, the HTTP server can be
* shut down with a custom HTTP <code>SHUTDOWN</code> request originating
* from the local host. The command line options for stopping an existing
* HTTP server are:
* <pre>
* [-port <var>port</var>] -stop
* </pre>

So, I'm not sure exactly how you shut it down if it was started with the
start.jar utility.  What is the correct parameter (-stop or -stoppable)
and what is a "custom HTTP SHUTDOWN request?

Since it's an HTTP server, I'd guess anything that you'd devise that
uses the 
protocol and requests a file would work.  You might imagine a local
process that 
has access to the file store which the server serves from, making
requests for 
files and checking what it receives against what it sees in the
directory perhaps.

Depends on how you start it.  If it's Administrable, then you could wire
that up 
to work, or use what is already in place if DestroyAdmin is implemented
by the 
object Administrable.getAdmin() returns.
