java - Bigbluebutton Java 安全问题

Question

我正在使用 bigbluebutton 0.8.1。我已经在本地（ubuntu 10.04）设置了开发环境，桌面共享工作正常。

后来我使用网址https://code.google.com/p/bigbluebutton/wiki/081DevelopingBigBlueButton#Developing_Deskshare创建了新的 bbb-desktop-applet jar 。然后将新创建的jar移动到ubuntu机器中的这个位置var/www/bigbluebutton/client，然后重新启动服务器。我可以创建和加入房间，但无法共享我的桌面，出现以下错误。我已经在 java 控制面板的异常站点列表中添加了 url，但它仍然无法正常工作。我遇到了这个问题。

I'm one of the developers of BigBlueButton.

You need to sign the modified desktop sharing jar file with a valid code signing certificate (not a self-signed certificate); otherwise, the browser will give you a very strong warning (such as the above) that warns the user they are trying to run an untrusted applet.

This is not a security issue with BigBlueButton; rather, it's the absence of a valid certificate signature with your modified desktop sharing applet.
