java – 您的安全设置已阻止使用已过期或尚未生效的证书签名的应用程序运行

我检查了上面的问题,但它没有帮助我,所以寻找其他解决方案.

几天前我们的applet代码签名证书已过期.我们更新了它,我再次创建了新的jar并用更新的证书签署了这个applet,现在我得到了一个例外.

我从Java控制面板中删除了所有现有证书,然后打开我们的网站,我在applet中获取新的证书详细信息.最新的到期日,但是当我点击Run它抛出异常时.

我再次检查了Java控制面板然后显示旧证书为什么Java没有使用新证书？

>转到控制面板 – > Java – >安全 – >编辑站点列表

添加应用程序URL,接受通配符.请注意,您可能必须关闭浏览器并重新开始,才能阅读新配置.

>在java控制面板安全性选项卡中,将安全级别降低到中,应用,确定并重新启动浏览器.它应该工作.
