用客户端调用的时候

import javax.naming.InitialContext;

import javax.naming.Context;

import javax.rmi.PortableRemoteObject;

import QueryInterface.*;

import QueryBean.*;

import java.util.*;

public class Test

{

public static void main(String[] args)

{

try

{

Properties env=new Properties();

env.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");

env.setProperty("java.naming.provider.url","localhost:1099");

InitialContext jndiContext = new InitialContext(env);

Object ref = jndiContext.lookup("QueryBean");

System.out.println("Got reference");

TestQueryHome home = (TestQueryHome)

PortableRemoteObject.narrow(ref, TestQueryHome.class);

QueryBean qb = home.create();

}

catch(Exception e)

{

System.out.println(e.toString());

}

}

}

执行的时候提示错误：

javax.naming.NoinitialContextException:Cannot instantiate class:org.jnp.interfaces.NamingContextFactory[Root exception is java.lang.ClassNotFoundException:org.jnp.interfaces.NamingContextFactory]

是我的初始化工厂地址错误吗？

麻烦老大了！
