当我尝试将远程客户端连接到服务器时，我收到此异常。我的服务器正在运行RMI服务器，并且没有安装防火墙。如何解决这个问题？

Answer 1

检查所有网络适配器，有时VM网络适配器会以这种方式干扰。您当前的localhost或127.0.0.1是哪个更不是指您的主机名或当前计算机，然后创建连接被拒绝的问题。我的一般建议是：

1.To check or disable unwanted VM or Network Adapters

2.Ping 127.0.0.1

3.Disable Firewall and Test if all the above doesn't work 

4.Add security Manager with a policy file on you server if you haven't done that.

Answer 2

您还没有提到您正在使用哪个操作系统，如果在代码和防火墙方面一切正确，那么您可能需要检查主机条目或IP表规则。

Answer 3

IPSERVER是否在/ etc / hosts文件中映射到您想要的IP地址？检查执行hostname -i或hostname时的效果。

尝试输入您的IP地址而不是域名。

Answer 4

尝试使用

启动RMI注册表

start rmiregistry

表示默认端口或

rmiregistry <port_no>

表示指定的端口。
