java.security.AccessControlException：访问被拒绝（“ java.security.SecurityPermission”“ authProvider.SunMSCAPI”）

Question

直到早上，我的applet一切正常。我进行了Java更新，一切都停止了。我正在使用小程序处理数字证书。这是我的堆栈跟踪。我关注了一些甲骨文文章，但没有用。

我正在用applet的.java.policy方法创建的[public void init()文件。在访问applet中的任何内容之前。

grant
{
permission java.security.AllPermission;
permission java.io.FilePermission "<<ALL FILES>>", "read";
permission java.io.FilePermission "<<ALL FILES>>", "write";
permission java.util.PropertyPermission "*", "read, write";
permission java.util.PropertyPermission "user.home", "read";
permission java.util.PropertyPermission "user.dir", "read";
permission java.lang.RuntimePermission "modifyThread";
permission java.lang.RuntimePermission "*";
};

更新：2013年11月18日

即使使用代码签名证书也不起作用

Answer 1

我还不能发表评论，所以我将其作为答案。

1. 我相信在applet中创建.java.policy文件为时已晚-插件将已经启动并在运行任何代码之前读取策略文件。

2. 您可以签名小程序并使用jnlp文件在安全元素中分配权限

Answer 2

我知道现在回答这个问题已经很晚了，但是添加我的解决方案是因为我在这方面遇到了困难：

我的问题：在部署依赖于Bouncy Castle库的应用程序（WAR文件）时，我遇到了这个问题：`

cannot create instance of
org.bouncycastle.jcajce.provider.digest.GOST3411$Mappings
 java.security.AccessControlException: access denied
("java.security.SecurityPermission"
"putProviderProperty.BC")

`

这是我所做的，对我有用：前往：{Installed JDK path}\jre\lib\security\打开文件java.policy

添加权限：permission java.security.SecurityPermission "putProviderProperty.BC";

重新启动程序以加载更改。

我还不了解它到底是如何工作的，或者只是像这样更改java.policy文件是否安全（仍在寻找实现这种配置的其他方法）。

请务必谨慎进行此类更改。甲骨文doc的更多内容>
