A question on state replication among clustered JBoss server

[mjkhan]

Hi, there.

I'm now involved in a project where JBoss servers are to be clustered and have a question on state replication among them.

I know that by clustering the servers, I can have, on state change, the state of an instance replicated to the other members of the cluster.

And I'm wondering if there is any way so that only modified objects are sent to the cluster's other members and let them synchronize themselves.

I'm putting this question because my SessionBean holds data that is huge in volume and frequent in change, it's going to be a costly operation, I think.

Does JBoss have any facility to address this issue?

Thanks in advance.

for your stateful session bean ; you have to implement a isModified method which the container will invoke b4 deciding to propogate the changes to other nodes.

I got around the problem by using a Message-driven Bean fetching the modified objects to the target SessionBean on state change.

Thanks anyway.
