Did they provide pricing information yet?
I played with it in the past, and it seemed like an interesting solution, but wouldn't invest too heavily in it because of pricing uncertainty.
> $0.02 per cloudlet per hour from ServInt, and 0.016 euro from dogado.
However, when you build your environment it still says 0$ regardless of the resources that you want, and has this clause at the bottom:
> Our prices will only be published at the official sales launch.

You have your standard Java WAR/EAR and deploy it to Jelastic via Maven or the classical web "upload this file please".
This is not Amazon nor GAE that would required you to do stuff.
