I’'m going to try to get a plugins page put up on the site over the next couple of days. Until then, you can use the broadcast plugin attached to this message. Simply download broadcast.jar and put it into the plugins directory of your Jive Messenger installation. The plugin will be automatically started. I plan to add a GUI configuration page for the plugin in a future version. For now, you must manually set properties to control it. Valid properties are (controllable through properties page of admin console):
plugin.broadcast.serviceName – name of the component. Default value is “broadcast”, which means broadcast.example.com, etc.
plugin.broadcast.groupMembersAllowed – true if group members should be allowed to broadcast messages to other group members. Otherwise, only group admins can broadcast messages. True by default.
plugin.broadcast.allowedUsers – bare JID’'s of users that are allowed to send broadcast messages to everyone. If this list is blank, anyone can send broadcast messages to everyone.
To use the service – send messages to either “all@broadcast.[yourserver]” or “[groupName]@broadcast.[yourserver]”.
Note: edited to remove attachment – new version is in message below
