java - JRE 1.7u45 无法加载包含一些未签名条目的小程序

Question

在 JRE 1.7u45 上加载 java applet 时出现以下错误。

此小程序确实包含一个未签名的条目。但是，由于第三方技术问题，我无法立即签署此条目。

同一个小程序在 JRE 1.7u40 上运行良好，但显然在 JRE 1.7u45 中有一些变化，增加了一些额外的安全特性。

我试图将 Java 中的安全级别降低到中等。这适用于 MAC，但不幸的是不适用于 Windows。

我们将不胜感激任何使小程序正常工作的建议/解决方法!

你必须禁用java临时文件

在窗口中:

1. 控制面板
2. Java
3. 常规标签
4. Internet 临时文件
5. 设置按钮
6. 列表项
7. 新对话框:临时文件设置对话框
8. 禁用选项:在我的计算机上保留临时文件。
