AWS ECS session replication

Hi,

I’m trying to set up a data grid on AWS ECS.

I was able to get JCache working with these tutorials:

But session replication is not working. I developed a very simple JSF webapp to test based on the hajspcluster demo, it has on web.xml and the session attributes are serializable.

What am I missing?

Thanks

HI @fkj,

We have a blog written regarding setting up session replication in Payara Server, although the blog is written as part of a series using Apache web server, the setup should still be applicable when using AWS ECS.

The blog can be found here: Session Replication in Payara Server with Hazelcast

If you are still unable to configure session replication after following that blog, I will gladly take a further look.

Thanks,
James

I followed these steps.

I can see some action at the logs, but when I stop one of the two instances of the test the session is lost
