I found some threads saying this was doable, but did not find specific instructions or config information.
I want to do this from Beanstalk as well: the app should get deployed to beanstalk with a config that points hibernate to the elasticache instance(s).
Yes, we were able to configure hibernate with 2nd level cache.. Not with beanstalk though.. This code should help you with it.
You would need the hibernate memcached jar as well
