Wanted to add that, the 4.0.3 admin guide seems to discourage the clustering of EJB 2.x entity bean.
And the entity bean clustering service in EJB 3.0 primarily deals with distributed caching and replication, instead
of load balancing.
Hence the question arised, whether its a good idea to cluster my CMP (2.x) entity beans, when both the clustered nodes will be reading and writing data possibly simultaneously.
Also will there be any disadvantages of using row-level locking ? Is it more prone to deadlocking issues?
