3.5.2 Creating the CORBA server Object

The Server object performs the following tasks:

• Initializes the CORBA server application, including registering factories, allocating resources required by the CORBA server application, and, if necessary, opening an XA resource manager.
• Performs CORBA server application shutdown and cleanup procedures.
• Instantiates CORBA objects required to satisfy CORBA client requests.

In CORBA server applications, the Server object is already instantiated and a header file for the Server object is available. You implement methods that initialize and release the server application, and, if desired, create servant objects.

The following code snippet includes the C++ code from the Simpapp sample application for the Server object.

static CORBA::Object_var static_var_factory_reference;
// Method to start up the server
CORBA::Boolean
Server::initialize (int argc, char *argv[])
{
  // Create the Factory Object Reference
  static_var_factory_reference = TP::create_object_reference (
      _tc_SimpleFactory->id (), "simple_factory", CORBA::NVList::_nil ());
  // Register the factory reference with the FactoryFinder
  TP::register_factory (static_var_factory_reference.in (),
                        _tc_SimpleFactory->id ());
  return CORBA_TRUE;
}
// Method to shutdown the server
void
Server::release ()
{
  // Unregister the factory.
  try
    {
      TP::unregister_factory (static_var_factory_reference.in (),
                              _tc_SimpleFactory->id ());
    }
  catch (...)
    {
      TP::userlog ("Couldn't unregister the SimpleFactory");
    }
}
// Method to create servants
Tobj_Servant
Server::create_servant (const char *interface_repository_id)
{
  if (!strcmp (interface_repository_id, _tc_SimpleFactory->id ()))
    {
      return new SimpleFactory_i ();
    }
  if (!strcmp (interface_repository_id, _tc_Simple->id ()))
    {
      return new Simple_i ();
    }
  return 0;
}
