This is a simple CORBA example that has an object (Time) with two
methods: one that returns the current time of day and another that
shuts down the server.  There are clients programs written in both C++
and Java to access the simple Time service.  The Java client uses
JACE's GetOpt class to parse the command line arguments.  See

for more details.

run_test.pl : This is a perl script to run the server and client as :
------------
	      server -o ior_file
	      client -f ior_file

This perl script runs the server and client and shuts down the server
when it is done.

Passing the Server IOR to Clients:
---------------------------------

To keep this example simple, the server advertises its IOR in the
following manner - The server program writes its server object's IOR
to a ior_file.  Later on, the client reads this IOR from the specified
ior_file and uses the <string_to_object> method to obtain a reference
to the server object.

For this mechanism to work, the file must be readable and writable. If
it doesn't exist, a new file is created by the server.  Moreover, the
file path must be accessible to both the client and server.

If the client and server are on different machine, then there must be
a shared directory accessible by both. On UNIX system's this is
typically done via the NFS mount command.  On Windows, the 'explorer'
application provides an option to share drives.

In general if no such file sharing option is available, then using the
the Naming Service mechanism is the only alternative, as descrbed by
the -n option below.

server:
-------

server [-nd] [-o <ior_output_file>]

Options:
-------
-o    Outputs the server ior to the file

When the server is started, you should see as the first line of output
something that looks like
        iiop:1.0//danzon.cs.wustl.edu:10015/P35ad159600081a38/child_poa/server
        (-ORBobjrefstyle url)
or
        IOR:000000000000001649444c3a43756269745...
        (-ORBobjrefstyle ior)

The -o option makes it easier to run from a script because the ior
passing is done through the <ior_output_file>.

-d    Debug flag
-n    Use the naming service

Using -d turns on debugging messages.  This option is additive, i.e.,
the more -d options provided, the more debugging you can get.  At the
moment, only 2 levels of debugging are implemented, and more than 2 -d
options are ignored.

client:
-------

client [-d] [-x] [-f <Server_ior_file>] [-n iterations] [-k ior]

Options:
-------
-d    Debug flag
-x    Tells the server to shutdown at the end of the test.
-f    Reads the server ior from the file
-n    Use the naming service
-k    IOR or The IOR can also be given in the format like file://[file.ior]
      with the full path

You can either cut and paste the IOR from the server to the client
(with the -k option), or have the client read the IOR from a file
using the -f option. (This file is produced using the -o option with the
server.)
