Fix WebEx Screen Share in Debian

In Debian, I was able to get the WebEx java applet to launch in Iceweasel with the help of OpenJDK, but I couldn't get screensharing to work properly. It just never came up when someone was sharing their screen and it wouldn't let me share my own.

Go ahead and install some 32-bit libraries, this should help:
Note: You must have multiarch enabled on your machine for this to work: sudo dpkg --add-architecture i386; sudo apt-get update

sudo apt-get install libgtk2.0-0:i386 libglib2.0-0:i386 libglib2.0-0:i386 openjdk-7-jre-headless:i386 libpango-1.0-0:i386 libpangoft2-1.0-0:i386 libpangox-1.0-0:i386 libxft2:i386 libxmu6:i386 libxt6:i386 libxv1:i386 openjdk-7-jre

Then launch your meeting again. Hopefully screensharing should work. I have heard reports of this not helping with meeting audio issues, but I don't use WebEx audio, I can't comment on that.

If that doesn't work, figure out what else you're missing with the help of this AskUbuntu post.

In case that post ever goes away, I've mirrored the steps here:

From this post, here is a step-by-step method that might work:

  1. Install JDK.
  2. Configure Java plugin for browser (no need for a 32-bit JDK or Firefox).
  3. Start a WebEx to create .so files inside $HOME/.webex/????/.
  4. Check for unresolved .so dependencies: ldd $HOME/.webex/????/*.so > $HOME/check.txt
  5. Search for missing libraries: grep "not found" $HOME/check.txt | sort | uniq
  6. Review the libraries; for example: => not found => not found => not found => not found => not found
  7. Find the corresponding packages: sudo apt-get install apt-file sudo apt-file update
  8. Locate that package that contains the missing libraries: apt-file search apt-file search
  9. Install the missing libraries, for example: sudo apt-get install -y libxmu6:i386 sudo apt-get install -y libasound2:i386 sudo apt-get install -y libxv1:i386 sudo apt-get install -y libxtst6:i386 sudo apt-get install -y libgcj12-awt:i386
