JRE 升级后 Java Applet 无法运行

Question

我有 JRE 1.6，已更新到 1.8.0_31。在此更新后，我的小程序已停止工作，并且出现以下错误

我正在使用 Jboss 服务器，并且 server.xml 文件已更新为使用正确的 keystore 和使用 SSL 的证书。

我已在浏览器和 JAVA 控制面板的异常(exception)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的证书。

请帮助了解解决步骤。

通过取消选中并重新选中 java 控制面板中的“在浏览器上启用 java 内容”复选框，我能够消除上述问题。 当外部用户使用该应用程序时，我仍然面临问题。

我观察到有两组异常 1、连接超时 2. 类未加载

所有这些问题仅在下载 JRE 版本 1.8.0_31-b13 后才出现

Also getting class not found as below

Ignored exception: java.lang.ClassNotFoundException: com.cosl.security.armor4c.api.MACApplet.class

任何有关这些的帮助都值得赞赏。我已经被这个问题困扰了 3 -4 周，并且没有任何可用的解决方案

Answer 1

您是否验证过您的证书是否存在垃圾字符？这似乎是一个证书错误。
