首先我启动注册表:

rmiregistry

然后从 Eclipse 我尝试执行服务器但收到此错误

then from eclipse I try to execute the server but get this error

我已经阅读了 RMI Java 教程，但仍然无法让它工作......

I've read the RMI Java tutorial but still could not get it working...

作为 VM 参数，我已设置:

As VM Arguments I've set this:

-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008

-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008

请帮帮我

推荐答案

从您的/bin、/build 或/build/classes 文件夹中运行 rmiregisrty 命令，无论哪个文件夹是您的根目录构建的文件.

Run the rmiregisrty command from your /bin, /build, or /build/classes folder, whichever folder is the root of your built files.

我花了半天时间试图解决同样的问题.

I spent half a day trying to solve that same thing.
