このファイルは,サンプルのbankでサーバ側のServerクラスをインプリメントします。コードサンプル4-4はC++のサーバ側プログラムの例です。コードサンプル4-5はJavaのサーバ側プログラムの例です。サーバプログラムは次のように動作します。
#include "BankImpl.h" int main(int argc, char* const* argv) { try { // Initialize the ORB. CORBA::ORB_var orb = CORBA::ORB_init(argc, argv); // get a reference to the rootPOA PortableServer::POA_var rootPOA = PortableServer::POA::_narrow( orb->resolve_initial_references("RootPOA")); CORBA::PolicyList policies; policies.length(1); policies[(CORBA::ULong)0] = rootPOA->create_lifespan_policy( PortableServer::PERSISTENT); // get the POA Manager PortableServer::POAManager_var poa_manager = rootPOA->the_POAManager(); // Create myPOA with the right policies PortableServer::POA_var myPOA = rootPOA->create_POA( "bank_agent_poa", poa_manager, policies); // Create the servant AccountManagerImpl managerServant; // Decide on the ID for the servant PortableServer::ObjectId_var managerId = PortableServer::string_to_ObjectId("BankManager"); // Activate the servant with the ID on myPOA myPOA->activate_object_with_id( managerId, &managerServant); // Activate the POA Manager poa_manager->activate(); cout << myPOA->servant_to_reference(&managerServant) << "is ready" << endl; // Wait for incoming requests orb->run(); } catch(const CORBA::Exception& e) { cerr << e << endl; return 1; } return 0; }
public class Server { public static void main(String[ ] args) { try { // Initialize the ORB. org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,null); // get a reference to the rootPOA POA rootPOA = POAHelper.narrow( orb.resolve_initial_references("RootPOA")); // Create policies for our persistent POA org.omg.CORBA.Policy[ ] policies = { rootPOA.create_lifespan_policy( LifespanPolicyValue.PERSISTENT) }; // Create myPOA with the right policies POA myPOA = rootPOA.create_POA("bank_agent_poa", rootPOA.the_POAManager(), policies ); // Create the servant AccountManagerImpl managerServant = new AccountManagerImpl(); // Decide on the ID for the servant byte[ ] managerId = "BankManager".getBytes(); // Activate the servant with the ID on myPOA myPOA.activate_object_with_id( managerId,managerServant); // Activate the POA manager rootPOA.the_POAManager().activate(); System.out.println( myPOA.servant_to_reference(managerServant) + "is ready."); // Wait for incoming requests orb.run(); } catch (Exception e) { e.printStackTrace(); } } }
