在开发TAO的命名服务中用到的服务端及客户端源代码。

DevGuideExamples/NamingService/corbaloc_Messenger/README

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

===================== IIOPLOC =================
REM iioploc: is TAO specific and deprecated

REM start the name server
cd/d %TAO_ROOT%\orbsvcs\Naming_Service
title NS
Naming_Service -ORBEndpoint iiop://localhost:2809 -m 0

REM -ORBInitRef with iioploc (TAO specific and deprecated)
MessengerServer -ORBInitRef NameService=iioploc://localhost:2809/NameService

cd/d %EXAMPLES%\NamingService\corbaloc_Messenger\Debug
title client
MessengerClient iioploc://localhost:2809/NameService

===== 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>
