Performing Operations

Finally, lets perform operations on the CORBA object.

  // make the hello_world object say hello.
  try {
    hello_world->sayHello();
  }
  catch (CORBA::SystemException exception) {
    cerr << "HelloWorld::sayHello";
    return -1;
  }

  // Read back what the hello_world object tells us...
  const char* prompt = "gimme something: ";
  CORBA::String message;
  try {
    CORBA::Long message_len =
        hello_world->readMessage(prompt, message);
    // print the read message
    cout << "readMessage returned '" << message << "'." << endl;
    cout << "   message size '" << message_len
         << "' characters." << endl;
  }
  catch (CORBA::SystemException exception) {
    cerr << "HelloWorld::readMessage";
    return -1;
  }
