Java RMI AccessControlException：访问被拒绝

Question

嘿AccessControlException: access denied，尝试启动正在编写的RMI应用程序时出现提示，我无法弄清楚为什么在默认端口1099或其他动态端口（当前是我的策略文件）上打开此异常时会出现此异常的原因授予所有权限（应用完成后会更改）。

我被困在哪里出了问题，任何帮助都会很有用

我的密码

public class Main {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) throws RemoteException, AlreadyBoundException, MalformedURLException {
     if (System.getSecurityManager() == null)
     {
        System.setSecurityManager ( new RMISecurityManager() );
     }

     CreditCardServer ccs = new CreditCardServer();

     int port = 1099;

     try {
        port = Integer.valueOf(args[0]);
        }
     catch (Exception e)
        {
        System.out.println("Invlaid Port");
        }

     if (((port <= 65535) && (port >= 49152)) || port ==1099)
     {
     System.out.println("Valid Port");
     }
     else
     {
         port = 1099;
        System.out.println("Port not in Dynamic Range 49152<-->65535");
     }

     System.out.println(port);

     LocateRegistry.createRegistry(port);

     LocateRegistry.getRegistry().bind("CreditCardServer", ccs);

     while (true)
     {
        //hum?
     }
}

}

堆栈跟踪

vega3 [ia32.linux] 23% java -Djava.security.policy=wideopen.policy -jar "BookStore-CreditCardServer.jar 65000"

有效端口

65000

我的政策文件

grant {
// Allow everything for now
permission java.security.AllPermission;
};

基本上，我很愚蠢，我认为因为Java并不抱怨它找不到.policy文件AOK，所以事实证明它没有将.policy文件的新副本移到工作目录中可以解决所有问题：-D
