java中远程对象方法调用中的安全策略问题

代码：
//////////////
package examples.RMIShape;
import java.rmi.*;
//import java.rmi.server.UnicastRemoteObject;
public class ShapeListServer {
    public static void main(String args[]){
         System.setSecurityManager(new RMISecurityManager());
        System.out.println("Main OK");
        try{
            ShapeList aShapelist = new ShapeListServant();
            System.out.println("After create");
            Naming.rebind("ShapeList", aShapelist);
            System.out.println("ShapeList server ready");
        }catch(Exception e) {
            System.out.println("ShapeList server main " + e.getMessage());
        }
    }

}
运行时：
Main OK
After create
ShapeList server main access denied (java.net.SocketPermission 127.0.0.1:109
9 connect,resolve)
请问怎么解决？
