I have discovered that the version available from the OpenFire website is slightly different from a source perspective to that which is available via jitsi. In particular there is a three parameter method in org.jitsi.videobridge.openfire.PluginImpl.initializePlugin in the OpenFire version and two parameters in the jitsi source (the Configuration manager is missing). I have bodged that and just ignored the third parameter for now.
I cannot fully test the Openfire implementation with the newer code as I am at home. The children are currently playing Minecraft and I will take them to the park soon. I will, therefore, be able to test this on Monday from my office.
However, when I run OfMeet it now does load the plugin (previously that failed), but gives an error message which a null pointer in the focus message and the focus goes wrong.
What this tells me is that there is more incompatible source which is out of phase. My question is:
Where could I find the code for videobridge that is compatible with the current plugin version of OpenFire?
