关于RMi的问题 ：access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)

[jxylook]

当我执行的时候，抛出异常
java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)

这该怎么解决阿？

下面是程序的代码：
服务器端：
1。PerfectTimeI.java

/*
* Created on 2004-11-23
*
* TODO To change the template for this generated file go to
* Window - Preferences - Java - Code Style - Code Templates
*/
package c15.rmi;

import java.rmi.*;



public interface PerfectTimeI extends Remote {

long getPerfectTime() throws RemoteException;

} ///:~

2.PerfectTimeI.java
/*
* Created on 2004-11-23
*
* TODO To change the template for this generated file go to Window -
* Preferences - Java - Code Style - Code Templates
*/
package c15.rmi;

import java.rmi.*;

import java.rmi.server.*;

import java.rmi.registry.*;

import java.net.*;

public class PerfectTime

extends UnicastRemoteObject

implements PerfectTimeI {

// Implementation of the interface:

public long getPerfectTime()

throws RemoteException {

return System.currentTimeMillis();

}

// Must implement constructor

// to throw RemoteException:

public PerfectTime() throws RemoteException {

// super(); // Called automatically

}

// Registration for RMI serving. Throw

// exceptions out to the console.

public static void main(String[] args)

throws Exception {

System.setSecurityManager(

new RMISecurityManager());

PerfectTime pt = new PerfectTime();

Naming.bind("//127.0.0.1:2005/PerfectTime", pt);

System.out.println("Ready to do time");

}

} ///:~

3客户端的代码：
DisplayPerfectTime.java

/*
* Created on 2004-11-23
*
* TODO To change the template for this generated file go to
* Window - Preferences - Java - Code Style - Code Templates
*/
package c15.rmi;

import java.rmi.*;

import java.rmi.registry.*;



public class DisplayPerfectTime {

public static void main(String[] args)

throws Exception {

System.setSecurityManager(new RMISecurityManager());

PerfectTimeI t =

(PerfectTimeI)Naming.lookup(

"PerfectTime");

for(int i = 0; i < 10; i++)

System.out.println("Perfect time = " +

t.getPerfectTime());

}

} ///:~

把客户端和服务器端的System.setSecurityManager(new RMISecurityManager())删了试试

[DNCS]

没有配置策略文件 grant{
permission java.security.AllPermission;
};

java -classpath F:\fuxuebaoinformation\JBTest\JNDAndRmi\test -Djava.rmi.server.codebase=file:/F:\fuxuebaoinformation\JBTest\JNDAndRmi\test\/ -Djava.security.policy=register.policy tt.Display

[DNCS]

把服务器中的System.setSecurityManager(new RMISecurityManager())删除,但是客户端的不能删除
