【问题描述】：

我的项目在到达 org.omg.CORBA.Object obj = orb.string_to_object(stringTarget); 时崩溃 并向我抛出一个异常，上面写着：“org.omg.CORBA.COMM_FAILURE：vmcid：SUN 次要代码：201 已完成：否”。 任何可能导致此错误的想法。 服务器在线，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);

【参考方案1】：

你需要define this property:

java.naming.factory.initial

根据错误信息

需要在环境或系统属性中指定类名，或者作为 applet 参数，或在应用程序资源文件中： java.naming.factory.initial

【讨论】：

我不确定这是根本原因。该错误看起来像是由于堆栈跟踪中更深层次的其他错误而引发的。这是我要关注的(COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: 10.40.56.100; port: 900

【参考方案2】：

运行 orb start orbd -ORBInitialPort 1050 或 tnameserv -ORBInitialPort 1050 运行您的课程客户端和服务器：-ORBInitialPort 1050 -ORBInitialHost localhost
