java -d参数 和 policy文件的问题

[KG071]

学习RMI，程序中有System.setSecurityManager(new RMISecurityManager());这样的代码，所以我设置了policy文件，文件的内容为：
grant {
permission java.security.AllPermission;
};

然后我在命令行下运行程序：
E:\test\rmi\server>java -Djava.security.policy=RMIpolicy.policy;-Djava.rmi.server.codebase=file:/.\/ UpperImpl
Exception in thread "main" java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099

因为权限问题报错，我估计是我的policy文件的问题，所以我特意在policy文件里加了一些杂乱的字母，然后再执行，还是报上面的错。肯定是policy文件的问题了。为什么policy文件会无效？ -d参数是按;还是空格隔开？我用空格不行 希望有人能帮忙解释下

没接触过

空格
内容太短了

file:/.\/ UpperImpl

file协议的路径看着不像这样

用绝对路径试试？

什么叫内容太短了？

这个问题解决了

是用空格分隔的 然后写绝对路径

然而出新的问题：UpperImpl_Stub.class是在服务器端的，在目录/server下
我执行E:\test\rmi\client>java -Djava.security.policy=RMIpolicy.policy UpperClient
出现如下错误：
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: UpperImpl_Stub

难道要把UpperImpl_Stub.class拷贝到/client下吗？如果那样还是远程调用吗？不知道这个该怎么解决

帮顶！我也想了解
