Is Singleton MDB possible in a cluster (EAP 6.2)

[drathnow]

I've read some old posts about creating a singleton MDB but I haven't been able to find any recent documentation on how to do this, or if it's even possible.  Specifically, what I need is an MDB that has a single active instance on one node in a cluster but if that node fails, a new MDB will be automatically started on another node in the cluster.

Is it possible to do this?  If so, can someone tell me how to do it or point me to some documentation that will tell me how to do it?  I'm using JBoss EAP 6.2 but not with the default HornetMQ messaging system.  I'm using the WebSphereMQ resource adapter instead.

Thanks.

Same problem here and not only with MDB Singletons even with Spring singleton beans.

Solution kindly requested .

The issue here is that the HASingletonDeployer is not implemented. Also there is no possiblitity to depend on a Barrier as before.

There is a request HA Singleton deployer for applications to implement such feature and deploy an application only at one cluster node.
