title: Bigbluebutton desktop sharing issue in java
body: <p>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.</p>
  
  <p>Later i created new bbb-desktop-applet jar, using the url
  <a href="https://code.google.com/p/bigbluebutton/wiki/081DevelopingBigBlueButton#Developing_Deskshare" rel="nofollow noreferrer">https://code.google.com/p/bigbluebutton/wiki/081DevelopingBigBlueButton#Developing_Deskshare</a>.
  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. Guide me here please.<img src="https://i.stack.imgur.com/dggWm.png" alt="enter image description here"></p>
