Java 从Jboss 5.1 EJB访问Jboss 7.1 EJB

我还有一个问题，非常感谢您的帮助：

Jboss 7.1中运行着一个EJB，需要从运行在Jboss 5.1上的另一个EJB访问它

我已经按照几页的说明做了。在Jboss 7.1中，我通过一个普通java类获得了与ejb的通信：

    final Properties jndiProperties = new Properties();  
    jndiProperties.put("java.naming.factory.initial","org.jboss.naming.remote.client.InitialContextFactory");  
    jndiProperties.put(InitialContext.PROVIDER_URL, "remote://127.0.0.1:4448");  
    jndiProperties.put("jboss.naming.client.ejb.context", true);  
    //jndiProperties.put(Context.SECURITY_PRINCIPAL, "client");  
    //jndiProperties.put(Context.SECURITY_CREDENTIALS, "password");  
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");  

    final Context context = new InitialContext(jndiProperties);  

    return (BeanRemoteInterface) context.lookup(LOOKUP_STRING); 

（我已将缺陷端口4447更改为4448，并取消了领域安全子系统的激活，因此现在不需要用户和通行证）

然而，当我在JBoss5.1中尝试从ejb进行通信时，它不起作用。我对InitialContext的创建进行了更改，经过多次测试，我发现了一个无法解决的错误：

12:15:13,219 ERROR [STDERR] javax.naming.CommunicationException: Could not obtain connection to any of these urls: remote://127.0.0.1:4448 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server remote://127.0.0.1:4448:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server remote://127.0.0.1:4448:1099 [Root exception is java.net.UnknownHostException: remote://127.0.0.1:4448]]]

顺便说一句！！！JBoss7.1使用-B0.0.0.0运行，所以这不是问题所在

提前谢谢
