omniORB C++服务器，Java 客户机在运行应用程序时出现问题

我在运行应用程序时遇到问题。我有一台服务器：

#include "Hello_impl.h"
#include <iostream>
#include <omniORB4/CORBA.h>
#include <omniORB4/Naming.hh>
using namespace std;
int main(int argc, char ** argv)
{
try {
// init ORB
CORBA::ORB_ptr orb = CORBA::ORB_init(argc, argv);
// init POA
CORBA::Object_var poa_obj = orb->resolve_initial_references("RootPOA");
PortableServer::POA_var poa = PortableServer::POA::_narrow(poa_obj);
PortableServer::POAManager_var manager = poa->the_POAManager();
// create service
Hello_impl * service = new Hello_impl;
// register within the naming service
try {
CORBA::Object_var ns_obj = orb->resolve_initial_references("NameService");
if (!CORBA::is_nil(ns_obj)) {
CosNaming::NamingContext_ptr nc = CosNaming::NamingContext::_narrow(ns_obj);
CosNaming::Name name;
name.length(1);
name[0].id = CORBA::string_dup("TestServer");
name[0].kind = CORBA::string_dup("");
nc->rebind(name, service->_this());
cout << "Server is running ..." << endl;
}
} catch (CosNaming::NamingContext::NotFound &) {
cerr << "not found" << endl;
} catch (CosNaming::NamingContext::InvalidName &) {
cerr << "invalid name" << endl;
} catch (CosNaming::NamingContext::CannotProceed &) {
cerr << "cannot proceed" << endl;
}
// run
manager->activate();
orb->run();
// clean up
delete service;
// quit
orb->destroy();
} catch (CORBA::UNKNOWN) {
cerr << "unknown exception" << endl;
} catch (CORBA::SystemException &) {
cerr << "system exception" << endl;
}
}

和客户：

import java.util.*;
public class client {
public static void main(String [] args) {
org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, null);
if (orb == null) System.exit(-1);
try {
// obtain service from naming server
org.omg.CORBA.Object ns_obj = orb.resolve_initial_references("NameService");
org.omg.CosNaming.NamingContext nc
= org.omg.CosNaming.NamingContextHelper.narrow(ns_obj);
org.omg.CosNaming.NameComponent [] path
= { new org.omg.CosNaming.NameComponent("TestServer", "") };
org.omg.CORBA.Object obj = nc.resolve(path);
Hello hello = HelloHelper.narrow(obj);
// use service
String server = hello.say_hello("Hello, omniORB C++ server, it's Java client");
System.out.println("Answer from server: " + server);
// destroy
orb.destroy();
} catch (org.omg.CORBA.ORBPackage.InvalidName exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.NotFound exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.CannotProceed exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.InvalidName exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CORBA.COMM_FAILURE exception) {
exception.printStackTrace(System.out);
} catch (Exception exception) {
exception.printStackTrace(System.out);
}
}
}

我像这样开始全名：

omniNames -start 6666 -logdir /home/mazix/Desktop/example/logs -errlog /home/mazix/Desktop/example/logs/omniNamesError.txt

然后，我启动我的服务器，如下所示：

./server -ORBInitRef NameService=IOR: .... (and here is my IOR num)

我启动客户端(在同一台计算机上(：像这样：

java client -ORBInitRef NameService=corbaloc::localhost:6666/NameService

它可以工作，但我想(需要(像这样启动我的服务器：

./server NameService=corbaname::localhost:6666

和克利内特：

java client -ORBInitialHost localhost -ORBInitialPort 6666

但是当我这样启动它时它不起作用：/

有什么帮助吗？:(

这是我的 omniORB 配置文件： http://www.2shared.com/document/dBAhFGLh/omniORB4cfg.html

除此之外，当

服务器在我的计算机上时，当客户端在我学校的计算机上时，我遇到了麻烦。他们"看不见"对方:(

好的，我知道：我没有启动我的 omniNames，但在我启动 omniNames 之前，端口 2809 上正在侦听某些东西，我检查了它，它：http://i47.tinypic.com/2d2ha9u.png

我认为没关系，我不需要通过输入终端"omniNames"来运行 omniNames 并且没有这样做

我只尝试像你说的那样运行我的服务器：http://i46.tinypic.com/2q2e33c.png

我试过这个：

运行我的全能名称：全名 -开始 6666
运行我的服务器： ./server -ORBInitRef NameService=corbaloc：：localhost：6666/NameService -ORBtraceLevel 40

并得到了这个：

java client -ORBInitialHost localhost -ORBInitialPort 6666

是一种用于查找本地命名服务的 ORACLE/SUN 特殊技术。更灵活和可移植的方法是对客户端和服务器使用 corbaloc 地址。这是在您的情况下：

java client -ORBInitRef NameService=corbaloc::localhost:6666/NameService
#and 
./server -ORBInitRef NameService=corbaloc::localhost:6666/NameService

对于客户端和服务器，您还可以分析 cmdline 参数以获得"更好"的接口，例如

java client localhost:6666
# and
./server localhost:6666

在这种情况下，您必须在运行时通过正常对象缩小或修补 ORB 配置/参数来交换对resolve_initial_references("NameService")的调用。(可根据要求提供示例(

如果客户端/服务器不在同一台计算机上运行，则必须将localhost与服务器的 IP 或公共名称交换，以换取命名服务和服务器。

什么是本地Hist？你是说本地主机吗？
据我所知，CORBA 客户端始终需要提供 IOR 或 corbaloc 字符串。也许您可以在本地配置它，但这可能是特定于客户端的。服务器的绑定应该是可配置的。
家庭计算机和学校计算机之间的问题可能与防火墙有关。如果您的学校 IT 部门没有防火墙未知入站流量，我会感到非常惊讶。连接到其网络上的随机计算机将属于此类别。
