警告: "IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: 10.88.129.159; port: 900"
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。

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：

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：liguoliang66@sohu.com,谢了！！！

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- -

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。

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。。

问题已经解决了，网上的例子有问题
应该是这么写
// A sample Java IDL object client application.
import java.util.Properties;

import org.omg.CORBA.ORB;
import org.omg.CosNaming.NamingContextExt;
import org.omg.CosNaming.NamingContextExtHelper;

import HelloApp.Hello;
import HelloApp.HelloHelper;
public class HelloClient
{
static Hello helloImpl;
public static void main(String args[]){
try{
// create and initialize the ORB
//String[] a={"–ORBInitialPort","80","–ORBInitialHost","10.88.129.155"};
// String nameservice = "corbaloc::10.88.129.155:5555/NameService";
// String[] a={"-ORBInitRef", "NameService="+nameservice };
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");
ORB orb = ORB.init(args, props);
// ORB orb = ORB.init(a, null);
System.out.println("ORB initialised\n");

// get the root naming context
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
// Use NamingContextExt instead of NamingContext,
// part of the Interoperable naming Service.
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);

// resolve the Object Reference in Naming
String name = "Hello1";
helloImpl = HelloHelper.narrow(ncRef.resolve_str(name));

// System.out.println("Obtained a handle on server object: " + helloImpl);
System.out.println(helloImpl.sayHello());
//helloImpl.shutdown();
}
catch (Exception e) {
System.out.println("ERROR : " + e) ;
e.printStackTrace(System.out);
}
} //end main
} // end class

[Quote=引用 2 楼 dxhangel 的回复:]
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
[/Quote]
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

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。
