对返回进行解组时出错；嵌套异常为：java.lang.ClassNotFound

我一直在使用RMI开发一个小程序，我想尝试将我的客户端作为一个jar进行测试（可能将它放在另一台计算机上，使用我自己的本地主机作为要连接的ip），但每次我用Intellij和VM选项编译它时：

-Djava.security.manager -Djava.security.policy=src/test.policy 

这是我的测试。政策：

grant {
permission java.security.AllPermission;
permission java.net.SocketPermission "*:1024-65535",
"connect,accept,resolve";
}; 

当我在Intellij中编译它时，在我放入主机（localhost）后，它会在标题中给我消息

error unmarshalling return; nested exception is: java.lang.ClassNotFound: ServerImplements_Stub

我想问的是，如何让它在jar中工作，或者甚至在Intellij中编译

这是我整个项目的代码

多谢各位

当我在Intellij中时，如果我直接从那里以“客户机”作为主文件构建程序，那就是当我收到此错误时。我唯一能正确运行程序的时间是使用java client在终端中运行客户端，或者单击finder中的client.class。如果我还没有说清楚，请告诉我我真的很想这样做，因为这将解决我未来的许多问题，谢谢！你还没有回答这个问题。我给了你三个选择。是哪一个？我建议您在问题中包含堆栈跟踪。EJP，我很抱歉，但我不明白您在这3个选项中的意思是什么？如果导出是指构建工件并将其变成一个罐子？当我把它变成一个罐子，它甚至不会启动。我不知道什么是绑定，什么时候查找。我非常感谢你花时间来帮助我，但你能详细说明一下吗？非常感谢您，我更改了代码中的System.setSecurityManager（new SecurityManager（））；对于新的RMISecurityManager，当我在intellij中运行它时，它可以工作，但当我导出（转到jar）时，我无法启动它
