Answer 1

http://u.115.com/file/f8d3172c4a 这个是服务器的源代码的下载地址

Answer 2

java.rmi.ConnectException: Connection refused to host防火墙问题？ 或是对应客户端的IP没设好？

Answer 3

server要访问远程资源么？rmi诶……

Answer 4

http://u.115.com/file/f8a1a350c4源代码的下载地址.

Answer 5

首先 
你把Socket(ip地址改成127.0.0.1，端口号不变）

Answer 6

java.rmi.ConnectException: Connection refused to host: 192.168.1.2;这句话就知道是连接主机的问题，主机地址是192.168.1.2。至于为什么是连接不上主机由很多情况，你需要提供更多的提示，比如是什么功能的代码，server是用的哪个（c/s结构貌似用本机做服务器就行了，顶多有个数据库），还有是在哪个步骤出错的（是连接服务器出错？还是启动服务器连接本机出错？还是远程访问服务器出错？）。你给的介绍明显不足，问题现在没法解决。

Answer 7

不是防火墙问题，也不是什么服务器的问题，应该是你的编译软件的环境路径没设置好，或者是安装的时候有些类包文件没安装上，这和c++mfc基本一样，第一 一般是你网上下载的编译软件不行；第二 软件版本和你电脑的系统不兼容而导致
