I hate to ask such a basic question but I can't seem to find this plugin as a War.
On the dev's website http://osflash.org/red5/red5downloads#red5_downloads he/she says it is not ready but I've see a few threads that have links to it that don't work. (ie: http://www.igniterealtime.org/community/message/181022#181022 )
I've had no problem setting up Openfire and Sparkweb on the latest build of Debian, but this little task is throwing me for a loop. I look forward to testing this plugin.
Thank you
Try this http://red5.4ng.net/gtms/red5-0.1.02.zip. Extract the file red5.war and install as an openfire plugin.
