Re: [gatein-dev] problem with replication
Just a clarification:
that does not prevent failover to happen as you could fail over on
another node of the cluster and lose your session.
what it prevents is the fault tolerance aspect attached to the fail
over operation.

Hi Julien,
I have created a jira for this https://jira.jboss.org/jira/browse/GTNPORTAL-339
so that we know it's there.
Yes, transitivity of serialization would definitely have been the
next problem and this needs to be looked at much higher level first
as you suggested. For now, I will temporarily postpone the
clustering and fail over testing. At least we have the setup ready,
so when things get working we would have a way to verify. ;-)
Cheers,

Hi Prabhat,
we are working at the management level at setting up things to work on
the fault tolerance aspect of GateIn clustering. For now, no such
development has yet begun.
Even if you could go beyond 1+2, you would hit the webui state stored
in the portal session that is not replicable.
I'll keep you informed when we have a more concrete roadmap on this
item.
cheers
ps: making everything serializable will lead to an error because of
the transitivity of the serialization nature.
