CORBA Echo Server

This is a primitive CORBA echo server (and client) in five languages, straight from the omniORB and Java tutorials:

http://omniorb.sourceforge.net/omni42/omniORB/index.html http://docs.oracle.com/javase/7/docs/technotes/guides/idl/jidlExample.html

All server appliations print their IOR and block then. All client applications take the IOR as command-line argument, connect to that servant and call the echo() routine once. You can now run the different client / servers against each other for some 'CORBA is cool' demonstrations. Check the demo.py script.

Everything is optimized to be small, including the Makefile's. Therefore, the usage of a naming service is ommitted.

Python

  • Install omniORB, test that it is available as Python package (import OMNIOrb).
  • Go into the ./python subdirectory.
  • (Optional) Re-generate stubs and skeletons with "omniorb -bpython ../echo.idl".
  • Start the server with "python server.py". It will print the server IOR to be used by the client.
  • Start the client with "python client.py ".

C++

  • Install omniORB.
  • Go into the ./cxx subdirectory.
  • (Optional) Re-generate stubs and skeletons with "omniorb -bcxx ../echo.idl".
  • Call "make" to build client and server.
  • Start the server with "./server". It will print the server IOR to be used by the client.
  • Start the client with "./client ".

C++11

  • Obtain and install TAOX11, see http://www.remedy.nl/en/taox11
  • Go into the ./cxx11 subdirectory.
  • Call "brix11 gen build" to generate the GNU makefiles
  • Call "make" to build the client and server
  • Start the server with "./server". It will print the server IOR to be used by the client.
  • Start the client with "./client ".

Java

  • Install a recent JDK.
  • Go into the ./java subdirectory.
  • (Optional) Re-generate stubs and skeletons with "idlj -fall ../echo.idl".
  • Call "make" to build the JAR files for client and server.
  • Run the server with "java -jar server.jar". It will print the server IOR to be used by the client.
  • Run the client with "java -jar client.jar ".

Ruby

  • Install R2CORBA, see http://www.remedy.nl/en/r2corba
  • Go into the ./ruby subdirectory.
  • No need to run an IDL compiler
  • Start the server with "ruby server.rb". It will print the server IOR to be used by the client.
  • Start the client with "ruby client.rb ".
