I am working in bigbluebutton 0.8.1. I had setup the development environment in my local(ubuntu 10.04) and desktop sharing is working fine.

Later i created new bbb-desktop-applet jar, using the url https://code.google.com/p/bigbluebutton/wiki/081DevelopingBigBlueButton#Developing_Deskshare. And then moved the newly created jar to this location var/www/bigbluebutton/client in ubuntu machine and then restarted the server. I can able to create and join the room, but not able to share my desktop, getting below error. Already I added the url in exception site list in java control panel but still it is not working.i stuck up with this issue.enter image description here

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.

  • Thanks for your reply Fred.Could you please explain how can we get valid code signing certificate. Also we are using only http protocol, not https. Please guide me here. Note - we are using below certificate to create the bigbluebutton jar. /home/firstuser/dev/bigbluebutton/deskshare/applet/tstcert.crt – sankar Jan 23 '15 at 05:17
