Thanks so much, I see that it is on the roadmap. Here are some files I have updated to try to create an eraser:

But when I try to login to the HTML5 client to test out the eraser, I'm getting this error. Any suggestions? TIA.

Hi Roger,
We recently updated our development docs for HTML5, see
Can you try the steps at the above link and let us know if you are able to make changes to the client and run them locally.
Regards,... Fred

That 500 error is before the HTML5 client gets involved also. You will sometimes see 500's from the demos if you just recently restarted BBB or bbb-web. If the 500 errors persist then you'll want to check that bbb-web is running and that bbb_api_conf.jsp is pointing to the correct IP/FQDN.

Thanks, Chad, it looks correct to me. When I check /var/lib/tomcat7/webapps/demo/bbb_api_conf.jsp it has values like:
// This is the URL for the BigBlueButton server
String BigBlueButtonURL = "https://tuberedu.ca/bigbluebutton/";
%>
<%!
// This is the security salt that must match the value set in the BigBlueButton server
String salt = "alasdflkwer0930502;laksdf902354iksdf ";
// This is the security salt that must match the value set in the BigBlueButton server
String salt = "alasdflkwer0930502;laksdf902354iksdf ";
// This is the URL for the BigBlueButton server
String BigBlueButtonURL = "https://tuberedu.ca/bigbluebutton/";
%>
When I try to run this from https://docs.bigbluebutton.org/2.2/dev.html
cd ~/dev/bigbluebutton/bbb-common-web
./deploy.shI get these values:

What do you suggest? I had just done a git fetch upstream yesterday.

Why are you trying to build bbb-web (and it's dependencies)? If you haven't made any changes to those files then you should just be using the packaged bbb-web.

I just realized that you posted the salt. If that's unmasked I would suggest changing it on your server. The other thing that's weird about the salt is that it has spaces in it. If you didn't add them for the post then I would recommend removing any whitespace from your salt. I would suggest only having alphanumeric characters in your salt.

More curiosity than anything. I thought that if I hadn't modified anything the bbb-common-web should at least still build and run from the dev version.

Thanks for the note, please note that I posted a "fake" salt

To build bbb-web you have to start one step higher to get bbb-common-message built. https://docs.bigbluebutton.org/2.2/dev.html#build-bbb-common-message

Hi Harsha,
> Hey did you manage to implement an eraser?
There isn't an eraser implemented in the BigBlueButton client yet, unless someone in the community has already implemented it and would like to share it with others. See
and
Regards,... Fred
