1.jre下面有个policytool的工具
2。生成.java.policy后，文件内容为
grant
{
permission java.net.SocketPermission "*","listen";
permission java.net.SocketPermission "*","accept";
permission java.net.SocketPermission "*","connect";
permission java.net.SocketPermission "*","resolve";
};应该可以搞定。

HelloServer err:RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: test_rmi.HelloImp1_Stubtest_rmi.HelloImp1_Stub这个HelloImp1_Stub类已经生成了啊！怎么回事呢？

E:\work\huangyuan_test\test_RMI\classes
-Djava.rmi.server.codebase=file:E:\work\huangyuan_test\test_RMI\classes\test_rmi -Djava.security.policy=file:E:\work\huangyuan_test\test_RMI\.java.policy
但是还是没有用！
HelloImp1 obj=new HelloImp1();
Naming.rebind("//127.0.0.1/HelloServer",obj);
System.out.println("HelloServer bound in registry");
}catch (Exception e){
System.out.println("HelloServer err:"+e.getMessage());
e.printStackTrace();
}
换成下面的代码试试看
try{
HelloImp1 obj=new HelloImp1();
Naming.rebind("//127.0.0.1/HelloServer",obj);
System.out.println("HelloServer bound in registry");
} catch (RemoteException ex){
Registry r = LocateRegistry.createRegistry(Registry.REGISTRY_PORT);
r.rebind("//127.0.0.1/HelloServer",obj);
}catch (Exception e){
System.out.println("HelloServer err:"+e.getMessage());
e.printStackTrace();
}
而是要通过
-Djava.rmi.server.codebase=file:/E:\work\huangyuan_test\test_RMI\classes/
指定
放在try块的外面就可以了。
不过我估计是路径的问题，有没有这样试过
不要把你的stub class的路径放到系统环境变量中的classpath中
而是要通过
-Djava.rmi.server.codebase=file:/E:\work\huangyuan_test\test_RMI\classes/
指定
这位MM学java多久了？不要一上来就用这种集成工具，这样会掩盖很多问题的。
用命令 rmiregistry
然后java -Djava.rmi.server.codebase=file:/E:\work\huangyuan_test\test_RMI\classes
/
-Djava.security.policy=java.policy
我想你出错的原因就在于
file:/E:\work\huangyuan_test\test_RMI\classes
/
你的codebase没有加两个反斜杠
3。就是运行你的客户端。不过你好像还没写哦
先在JBuider里，改改看，主要是CODEBASE
-Djava.rmi.server.codebase=file:/E:\work\huangyuan_test\test_RMI\classes\test_rmi/-Djava.security.policy=file:/E:\work\huangyuan_test\test_RMI\.java.policy(HelloImp1_Stub.class)
要运行的就是这个类嘛，对了，请问你是怎么运行的？
和classpath的概念，另外就是
(HelloImp1_Stub.class)太让我意外了
抛开参数不管，要运行一个一般的class也是要写成
java xxx这种形式啊
你怎么要加括号呢？搞不懂，这个名字就是我上面说的test_rmi.HelloImp1
也就是你的server class的全名
