java applet找不到类,从未找到Java applet类

我遇到了所有三种主流浏览器的java插件问题：chrome，firefox和Internet Explorer。 问题是，无论我尝试使用什么网站或applet，applet总是无法加载并产生错误。 我在oracle的网站上看不到任何示例小程序; 我无法启动minecraft浏览器小程序; 我也无法使用任何浏览器在网络上启动任何小程序。

I am having a problem with the java plugins of all three major browsers: chromium, firefox and Internet Explorer. The issue is that applets will always fail to load and yield errors no matter what website or what applet I am trying to use. I can not see any of the example applets on oracle's website; I can not launch the minecraft browser applet; nor can I launch any applet across the web using any browser.

我总是收到"未找到的类：AppletClassHere.class" 错误。 我知道我的浏览器插件必须正常工作，因为每次连接到我的网络时都可以启动Cisco Nac applet，我可以离线启动自己的简单applet。

I always receive a "class not found:AppletClassHere.class" error. I know that my browser plugin must be working correctly because I can launch the Cisco Nac applet each time I connect to my network and I can launch my own simple applets offline.

如果重要的话，我通过vpn连接到互联网。 我认识的很多其他人似乎都有这个问题。

I am connecting to the internet through a vpn in case that is important. It also seems like a lot of other people I know are having this issue.

重新安装插件似乎无法解决问题。 我问这个问题是为了找出这个问题的原因，以及任何可能的解决方案。

Re-installing the plugin does not appear to fix the issue. I am asking this question to find out the cause of this problem, and any possible solutions.
