java某些用户遇到安全异常：试图将沙盒jar作为TrustedLibrary打开

1 周，3 日 Questions & Answers 26380

我们在应用程序登录页面上使用applet。小程序包含2个类。Jar已签名（ca证书）。清单文件包含：“受信任的库：true”

它适用于大多数用户，但其中一些用户在applet方面存在问题，因为JVM报告安全异常：试图将沙盒jar作为受信任的库打开

你知道为什么对他们不起作用吗

例如，User1在10.21.2.11中有Java插件 JRE版本1.7.0_21-b11 Java热点（TM）客户端虚拟机。他尝试Firefox21和IE 8.0.6001.18702

JVM报告一般异常：

我们也有类似的问题。对我们来说，问题在于jre\lib\security\java。客户端计算机上的策略文件已修改，添加了：
```
grant {
    permission java.security.AllPermission;
};
```
如果删除此选项，错误就会消失。在我们的测试中，如果我们删除了Trusted Library，错误也会消失：true，但考虑到新的Java小程序规则，这并不是一个真正的选项

有 Java 编程相关的问题?
