[jboss-user] [EJB 3.0] - Clustered Singleton

[apwalker]

I'm trying to create a HA-Singleton service and was wondering if new @Service annotation can be used with an @Clustered annotation and if so what is the semantic for the cluster behavior 

So if I have something like


  | ...
  | @Service
  | @Clustered
  | public MyService implements MyServiceManagement 
  | {
  | .....
  | }
  | 

Does this mean that I have once instance active on each node of the cluster or a single instance active in the entire cluster. If the latter then does it handle the HA failover protocol the same way the HASingletonSupport class does.

cheers

Aaron
