在 JRE 1.7u45 上加载 Java 小程序时出现以下错误.

I am getting the following error while loading a java applet on JRE 1.7u45.

这个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.

This applet indeed contains one unsigned entry. However I cannot get this entry signed immediately because of third party technical issues.

同一个小程序在 JRE 1.7u40 上运行良好，但显然在 JRE 1.7u45 中进行了一些更改，添加了一些额外的安全功能.

The same applet worked fine on JRE 1.7u40, but apparently there has been some change in JRE 1.7u45 adding some additional security features.

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.

I tried to reduce the security level in Java to medium. This works on MAC but unfortunately does not work on windows.

任何使小程序正常工作的建议/解决方法将不胜感激！

Any suggestions/workaround to get the applet to work would be greatly appreciated!

推荐答案

您必须禁用 java 临时文件

You have to disable the java temporary files

在窗口中:

1. 控制面板
2. java
3. 常规标签
4. 临时 Internet 文件
5. 设置按钮
6. 列表项
7. 新建对话框: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.
