这是为什么呢 我曾把端口号改成了5555 结果还是报读的端口号是900请高手来一起看看到底是什么问题 我就是通过客户端访问10.88.129.155 端口 80的服务器
老是连接失败。

Answer 1

这个错误信息里面的ip应该是你本机的ip和端口。
该错误信息只是描述了连接失败，并没有显示失败的原因。
还有没有错误信息。

Answer 2

ERROR : org.omg.CORBA.COMM_FAILURE:  vmcid: SUN  minor code: 201  completed: No
org.omg.CORBA.COMM_FAILURE:  vmcid: SUN  minor code: 201  completed: No 
这个地方应该是抛出的错误信息的描述
这个错误应该是jndi有问题。
看有没有j2ee.jar，修改一下jndi.properties文件.
java.naming.provider.url默认的是localhost

Answer 3

我在本地启动客户端和服务器可以相连的，在客户端我看了没有j2ee.jar应该在那里找呢

Answer 4

问题已经解决了，网上的例子有问题
应该是这么写

Answer 5

远程访问是需要使用JNDI来进行远程寻址的。
连接远程对象之后才能进行通信。
所以我首先考虑的是你的JNDI的配置是否有问题。
祝贺你
白让我忙了打字了。。

Answer 6

我的问题和你的很类似 
jacorb开发corba，客户端和服务端同时在win下或者linux下运行没有问题。  但是服务器端放到linux下，客户端win就发生了无法响应的情况。 

Answer 7

Properties props = new Properties();   
  // 生成一个ORB，并初始化，这个和Server端一样   
  props .put("org.omg.CORBA.ORBInitialPort", "1050");   
  props.put("org.omg.CORBA.ORBInitialHost", "10.88.129.155"); 这几句让我找了很久- -  

Answer 8

我是corba的初学者，谁能给我个在Unix/linux上jacorb的安装文档啊？一直在linux上没有安装成功，小弟邮箱：[email protected],谢了！！！

Answer 9

能把整个helloCorba发给我吗？[email protected]

Answer 10

我也出现了同样的问题，按照你的代码修改后又出现了另外的问题，应该是这句：
org.omg.CORBA.Object ncObj = orb.resolve_initial_references("NameService");
报以下的错误：
