java - 为什么会出现NamingContextPackage.NotFound异常？

我是CORBA的新手。当我运行以下代码时，我得到：


  线程“主”中的异常
  org.omg.CosNaming.NamingContextPackage.NotFound：
  IDL：omg.org/CosNaming/NamingContext/NotFound：1.0


排队：

ncRef.rebind(factoryName,  rootpoa.servant_to_reference(sessionFactoryServant));

码：

final String initHost = System.getProperty("org.omg.CORBA.ORBInitialHost",
        java.net.InetAddress.getLocalHost().getHostAddress());
    if (StringUtils.isNotBlank(initHost) == true)
    {
        properties.put("org.omg.CORBA.ORBInitialHost", initHost);
    }

    //final String initPort = System.getProperty("org.omg.CORBA.ORBInitialPort");
    final String initPort = "1051";
    if (StringUtils.isNotBlank(initPort) == true)
    {
        properties.put("org.omg.CORBA.ORBInitialPort", initPort);
    }

    // Start the ORB.
    m_orb = ORB.init(m_arguments, properties);

    POA rootpoa = POAHelper.narrow(m_orb.resolve_initial_references("RootPOA"));
    rootpoa.the_POAManager().activate();

    final RSSessionFactoryServant sessionFactoryServant = new RSSessionFactoryServant(rootpoa);
    rootpoa.activate_object(sessionFactoryServant);


    org.omg.CORBA.Object objRef = m_orb
            .resolve_initial_references("NameService");
    System.out.println("Name server is " + objRef + ".");

    NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);
    System.out.println("Naming context is " + ncRef + ".");

    final NameComponent[] factoryName = getSessionFactory();    // Contains name components.. nothinf seems wrong here
    System.out.println("Session Factory is [" + ArrayUtils.toString(factoryName) + "].");

    ncRef.rebind(factoryName,  rootpoa.servant_to_reference(sessionFactoryServant));

    System.out.println("Server ready and waiting ...");

     m_orb.run();

最佳答案

命名服务不知道您要搜索的对象。因此，您将获得NotFound异常。您可能要在第一步中使用bind。
