Dear OpenMeetings Developers,
We would appreciate your insights into our screensharing tests in OM
3.1.0. When we run the downloaded public_#.jnlp file (see below), we
get the following test results where first two succeed, and third one
fails (Exception Log included below). Application.base.url settings were
changed suitably for each test case:
(1)Within LAN (using local DNS URL): works fine.
(2)From WAN (using <FQDN:5080> in URL): works fine.
(3)From WAN (using <FQDN> with reverse proxy): it gives “*Unable
*to launch openmeetings screensharing applet” in the dialog popup.
OM 3.0.6 works fine in the same environment.
OM 3.0.7 worked fine. But while downloading screensharing applet it
used to expose the port number <FQDN:5080> even in reverse proxy scenario.
-------------
Current environment:
OM 3.1.0
Server 1: CentOS 6.5, MySQL
Server 2: CentOS 7, MariaDB
Java 7 patch 76
