OSGi Event Broadcasting support (eventadmin)
Apache Karaf Cellar is able to listen all OSGi events on the cluster nodes, and broadcast each events to other nodes.
Enable OSGi Event Broadcasting support
OSGi Event Broadcasting is an optional feature. To enable it, you have to install the cellar-eventadmin feature:
karaf@root()> feature:install cellar-eventadmin
OSGi Event Broadcast in action
As soon as the cellar-eventadmin feature is installed (on all nodes that should use the clustered eventadmin), Cellar listens all OSGi events, and broadcast these events to all nodes of the same cluster group.
