问题描述

我在applet.I政策文件的设置问题，我做这一次，不知道如何设置策略文件的小程序java.Actually我想给权限的小程序上写文件系统。为此我将不得不放弃文件权限的小程序

I have problem in setup of policy file for applet.I am doing this first time and don't know how to set the policy file for applet in java.Actually I want to give the permission to the applet to write on the file system. for Which I will have to give file permission to the applet

于是我做出的.java.policy文件命名，并把下面的code在它

So I make a file named .java.policy and and put the following code in it

grant codeBase "file:/C://res/applet/*" {
permission java.io.FilePermission "C:\\res\\applet\\test.txt", "read, write";
};

和它保存在用户\\文件夹金达莱现在我设置JAVA_HOME为
C：\\用户\\金达莱

and save this in users\jindal folder now i set the JAVA_HOME as c:\users\jindal

但我仍然发现异常

java.security.AccessControlException：
  访问被拒绝（java.io.FilePermission中
  C：\\ RES \\小程序\\ test.txt的写入）

java.security.AccessControlException: access denied (java.io.FilePermission C:\res\applet\test.txt write)
