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.

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，我无法立即使该条目签名.

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

相同的applet在JRE 1.7u40上运行良好，但显然JRE 1.7u45进行了一些更改，增加了一些其他安全功能.

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的安全级别降低到中等水平.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Windows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. 新建"对话框:临时文件设置"对话框
8. 禁用该选项:将临时文件保留在我的计算机上.
