RMI简单程序，运行不了，帮忙看看

远程接口程序：  
  package   helloWorld;  
   
  import   java.rmi.Remote;  
  import   java.rmi.RemoteException;  
   
  public   interface   Hello   extends   Remote   {  
  String   sayHello()   throws   RemoteException;  
  }  
   
  远程接口实现：  
  package   helloWorld;  
   
  import   java.rmi.Naming;  
  import   java.rmi.RemoteException;  
  import   java.rmi.RMISecurityManager;  
  import   java.rmi.server.UnicastRemoteObject;  
   
  public   class   HelloImpl   extends   UnicastRemoteObject   implements   Hello   {  
  public   HelloImpl()   throws   RemoteException{  
  super();  
  }  
   
  public   String   sayHello()   {  
  return   "Hello   RMI   World!";  
  }  
   
  public   static   void   main(String[]   args)   {  
  if   (System.getSecurityManager()   ==   null)   {  
  System.setSecurityManager(new   RMISecurityManager());  
  }  
   
  try   {  
  HelloImpl   obj   =   new   HelloImpl();  
   
  Naming.rebind("//localhost:1099/HelloServer",obj);  
  System.out.println("HelloServer   bound   in   registry!");  
  }catch   (Exception   e)   {  
  System.out.println("HelloImpl   err"+e.getMessage());  
  e.printStackTrace();  
  }  
  }  
  }  
   
   
  start   rmiregistry后运行java   helloWorld.HelloImpl就抛出异常：  
   
  HelloImpl   erraccess   denied   (java.net.SocketPermission   127.0.0.1:1099   connect,resolve)

删除代码：  
  if   (System.getSecurityManager()   ==   null)   {  
  System.setSecurityManager(new   RMISecurityManager());  
  }  
   
  如果你一定要使用security   manager，则需要自己编辑policy文件。  
  具体做法找一下java相关文档，有很多介绍的。Top

如果是本地测试的话，是不能用localhost的，必须要用你的计算机名。Top
