Hi, I am looking for 'something' that: - has the features of a SFSB (statefull, can be clustered) - runs as a singleton I have investigated a lot the Service bean (the jboss extension) but unfortunately it does not support replication (am i right?). I would like to implement a system that consist of a set services that collaborate between each others. When an instance of a service fails, I would like the system to able to failover another box.
