Data replication isn't supported in any of the latest versions. I can only assume it was removed after 2.1.2 because it wasn't fully functional. Data replication should be HornetQ 3.0 (if not sooner).
And anyone has any idea when we will have HornetQ 3.0? Or other version with data replication?
We just talked about wrapping up what we did and going towards a 2.3.0. Beta
We were busy with AS7 releases which was based on 2.2 which was dragging our resources. Now we are done we are moving towards 2.3.0 faster now. We don't have a date yet.. we need to see what is needed to change the examples.
If anyone is whilling to help on fixing the examples, stop by #hornetq on freenode
