客户端运行不了，急！！！

[h_q_l]

我用SUN公司的J2EE服务器部署了一个session bean，JNDI中名称为ConverterBean

我的客户端的写法如下：

Context initial = new InitialContext();
Object objref= initial.lookup("java:comp/env/ejb/ConverterBean");

ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);

Converter currencyConverter = home.create();


使用java运行的时候总提示我

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

要如何修改可以运行？

magic，如果你不设置initial context的参数：javax.naming.Context.INITIAL_CONTEXT_FACTORY和javax.naming.Context.PROVIDER_URL，谁知道你要访问哪个服务器的jndi

我修改了代码，加上了几句

env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://127.0.0.1:4848");

Context initial = new InitialContext(env);
Object objref= initial.lookup("java:comp/env/ejb/SimpleConverter");

ConverterHome home =(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);

Converter currencyConverter = home.create();

错误转换成如下：

javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 208 completed: Maybe]
