// $Id$
DevGuideExamples/NamingService/corbaloc_Messenger/README
// $Id$
The example in this directory extends the example in GettingStartedUNIX
(or GettingStartedVC) to use the Naming_Service
and calling string_to_object instead of calling resolve_initial_references
to get the NameService object reference.
This example only differs from the NamingService/Messenger example by a few lines
in the MessengerClient.cpp. (All other source files should be the same.)
How to Run:
-----------
To start the Naming_Service:
----------------------------
$TAO_ROOT/orbsvcs/Naming_Service/Naming_Service -m 1 &
Note: Must start the Naming_Service using multicast (-m 1)
for the default initial reference for NameService to work.
To start the server:
------------------
./MessengerServer
To start the client:
------------------
./MessengerClient
This MessengerClient will optionally take parameter that is a URL (corbaloc:)
that addresses the Naming_Service.
The MessengerServer and MessengerClient may also take an -ORBInitRef option
to help qualify the address of the Naming_Service.
Here are some examples:
REM start the name server
cd/d %TAO_ROOT%\orbsvcs\Naming_Service
title NS
Naming_Service -ORBEndpoint iiop://localhost:2809 -m 0
REM start the example server
cd/d %EXAMPLES%\NamingService\corbaloc_Messenger\Debug
title server
REM use -ORBInitRef with IIOP
MessengerServer -ORBInitRef NameService=iiop://localhost:2809/NameService
REM use -ORBDefaultInitRef with specific host and port
MessengerServer -ORBDefaultInitRef iiop://localhost:2809
REMuse -ORBDefaultInitRef <port 2809 is the default if not specified.
MessengerServer -ORBDefaultInitRef corbaloc::localhost
REM crashes - ? is this a bug?
MessengerServer -ORBDefaultInitRef corbaloc:rir:/
REM -ORBInitRef with corbaloc and default port
MessengerServer -ORBInitRef NameService=corbaloc::localhost/NameService
REM and specific port
MessengerServer -ORBInitRef NameService=corbaloc::localhost:2809/NameService
REM crashes
MessengerServer -ORBInitRef NameService=corbaloc:rir/NameService
REM start the client
cd/d %EXAMPLES%\NamingService\corbaloc_Messenger\Debug
title client
MessengerClient -ORBInitRef NameService=iiop://localhost:2809/NameService corbaloc:rir:/NameService
REM use -ORBDefaultInitRef with specific host and default port == 2809
MessengerClient -ORBDefaultInitRef corbaloc::localhost corbaloc:rir:/NameService
REM use a corbaloc that does not require -ORBDefaultInitRef (port defaults)
MessengerClient corbaloc::localhost/NameService
===========================
REM !!! kill the previous Naming_Service and MessengerServer !!!
REM start the name server (at another address)
cd/d %TAO_ROOT%\orbsvcs\Naming_Service
Naming_Service -ORBEndpoint iiop://localhost:9999 -m 0
REM start the example server
cd/d %EXAMPLES%\NamingService\corbaloc_Messenger\Debug
MessengerServer -ORBInitRef NameService=iiop://localhost:9999/NameService
REM start the client
cd/d %EXAMPLES%\NamingService\corbaloc_Messenger\Debug
MessengerClient -ORBInitRef NameService=iiop://localhost:9999/NameService
MessengerClient -ORBInitRef NameService=iiop://localhost:9999/NameService
Usage: MessengerClient [-ORB options] [corbaname URL for the name service]

===== MCAST example ======
!!! only on platforms supporting multicast (not Windows) !!!
# start the name server using MultiCast
cd $TAO_ROOT/orbsvcs/Naming_Service
Naming_Service -m 1
# start the example server
cd $EXAMPLES/NamingService/corbaloc_Messenger
MessengerServer
cd $EXAMPLES/NamingService/corbaloc_Messenger
MessengerClient
--- specify the multicast address.
Naming_Service -m 1 -ORBNameServicePort 12345
# -ORBNameServicePort 12345 is ingored if -m 1 is not specified.
MessengerServer -ORBInitRef NameService=mcast://:12345::/NameService
<TBD more using URL parameter>
