一道Java RMI的题，高手请进！！

Question

interface anyName extends Remote {//定义远程对象，客户端和服务器端共享
        void someMethod() throws RemoteException { ... }
        ...
}
//服务器端
//anyNameImpl.java
public class anyNameImpl extends UnicastRemoteObject implements anyName {
        public anyNameImpl( String d ) { descr = d; }
        public void someMethod() throws RemoteException { ... }        private String descr;
}//anyNameServer.java
public class anyNameServer {
        public static void main( String args[] ) {
                try {
                        System.out.println( "Constructing server implementations..." );
                        anyNameImpl p = new anyNameImpl( "Name1" );
                        System.out.println( "Binding server implementations to registry..." );
                        Naming.rebind( "p",p );                        System.out.println( "Waiting for invocations from clients..." );
                }
                catch( Exception e ) { }
        }
}//客户端
//anyNameClient.java
public class anyNameClient {
        public static void main( String args[] ) {
                System.setProperty( "java.security.policy","client.policy" );
                System.setSecurityManager( new RMISecurityManager() );                String url = "rmi://localhost/";                try {
                        anyName p = (anyName)Naming.lookup( url + "p" );
                        p.someMethod();
                }
                catch( Exception e ) { }
        }
}运行就自己看书了，先启动注册服务器，然后编译服务器端，然后启动服务器，然后运行客户端。多看看书。
