Second witheboard issue
Hi Guys,
If someone, i'm using ubuntu 16.04 LTS, with OM 4.0.0 and i've
follow the tutorial provided by Alvaro how to install 4.0 on Ubuntu
16.04 LTS ( Installation OpenMeetings 4.0.0 on Ubuntu 16.04 LTS.pdf
<https://cwiki.apache.org/confluence/download/attachments/27838216/Installation%20OpenMeetings%204.0.0%20on%20Ubuntu%2016.04%20LTS.pdf?version=2&modificationDate=1510068466000&api=v2>
) .
I've deleted everything and reinstall everything twice. On the demo
server it's working. But i don't know where to look at in my
configuration as i don't see any mistake, if someone could help.
When i enter in the room, for the first whiteboard everything is fine.
It's working perfectly, i can add pdf files without issues. If i open a
second a whiteboard and try to upload a pdf or image it's doenst work. I
get like it's loaded but nothing appear in the whiteboard stay white
with the number of page of the pdf appearing that it.
My java version
java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
On my open meeting log file i get the following error :
ERROR 11-20 14:24:32.544 o.a.w.DefaultExceptionMapper:170
