CORBA orb.resolve_initial_references（“ ORBPolicyManager”）; 不起作用

Question

當我的項目到達org.omg.CORBA.Object obj = orb.string_to_object（stringTarget）;時，我的項目崩潰了。 並拋出一個異常，說：“ org.omg.CORBA.COMM_FAILURE：vmcid：SUN次要代碼：201已完成：否”。 任何可能導致此錯誤的提示。 服務器在線，我可以Ping它。 我的IOR文件已更新。

  Properties props = System.getProperties();

        props.put("org.openorb.PI.FeatureInitializerClass.org.openorb.orb.messaging.MessagingInitializer","");
        props.put("ORBClass", "org.openorb.orb.core.ORB");
        props.put("iiop.port", ParameterUtil.getInstance().getOrbClientPort());
        props.put("iiop.useNativeLibrary", "true");

        // Inicializa o ORB
        if (orb == null) {
            synchronized (semaforo) {
                if (orb == null)
                    orb = ORB.init(args, props);
            }
            logger.info("ORB inicializado.");
        }



                    FileInputStream file = new FileInputStream(Constantes.IOR_FILE_PATH);

        BufferedReader myInput = new BufferedReader(new java.io.InputStreamReader(file));
        String stringTarget =  myInput.readLine();
        logger.debug("IOR used is :" + stringTarget);

        org.omg.CORBA.Object obj = orb.string_to_object(stringTarget);

        // Definição de politica de timeout no ORB
        try {
            PolicyManager opm = (PolicyManager) orb.resolve_initial_references("ORBPolicyManager");
            Any time_any = orb.create_any();
            // convert from 1ms to 100ns
            org.omg.TimeBase.TimeTHelper.insert(time_any, orbTimeout * 1000 * 10);
            Policy[] policies = new Policy[1];
            policies[0] = orb.create_policy(org.omg.Messaging.RELATIVE_RT_TIMEOUT_POLICY_TYPE.value, time_any);
            opm.set_policy_overrides(policies,
                    SetOverrideType.ADD_OVERRIDE);
        } catch (InvalidName invname_ex) {
            logger.error("ORBPolicyManager wasn't found! (" + invname_ex + ")");
        } catch (PolicyError pol_ex) {
            logger.error("A policy error occured: " + pol_ex + " - Reason Code: " + pol_ex.reason, pol_ex);
        } catch (InvalidPolicies invpol_ex) {
            logger.error("An invalid policy has been specified: " + invpol_ex);
        }

這是完整的堆棧跟蹤

Answer 1

您需要定義此屬性 ：

java.naming.factory.initial

根據錯誤消息

需要在環境或系統屬性中或作為applet參數或在應用程序資源文件中指定類名稱：java.naming.factory.initial

Answer 2

1. 運行orb start orbd -ORBInitialPort 1050或tnameserv -ORBInitialPort 1050
2. 使用以下命令運行類客戶端和服務器： -ORBInitialPort 1050 -ORBInitialHost localhost
