我有JRE 1.6，更新到1.8.0_31。在此更新后，我的applet已停止工作，我收到以下错误

我正在使用Jboss服务器，并且已更新server.xml文件以使用SSL使用正确的密钥库和证书。

我在浏览器和JAVA控制面板的例外列表中添加了我尝试访问的https站点。清除了两者的缓存并删除了用户证书以确保下载最新证书。

请帮助了解解决步骤。

通过取消选中并检查＆＃34;在浏览器上启用java内容，我能够删除上述问题＆＃34;复选框在java控制面板中。 当外部用户使用该应用程序时，我仍然面临着问题。

我观察到有两组例外 1.连接超时 2.班级没有加载

所有这些问题仅在下载JRE版本1.8.0_31-b13

Also getting class not found as below

对此有任何帮助表示赞赏。我坚持这个问题，因为3-4周以来没有任何解决方案

1 个答案:

答案 0 :(得分：0)

您是否为任何垃圾字符验证了您的证书？这似乎是证书错误。
