    //etc

我之前遇到过这个问题，我修复它的方法是通过添加此行来允许我的java.policy中的所有权限。

   grant {
     permission java.security.AllPermission;
   };

这解决了之前的问题，但现在不再有用了。

这一行以上的一切都无关紧要：

java.net.ConnectException: Connection refused: connect

这只是意味着您的applet在网络级别遇到问题（不 Java安全性）。它所连接的主机拒绝连接，这通常意味着没有服务监听host:port。

在我的机器上更新JRE后，Applet无法正常工作
