As far as I know - there is no official annoucement yet, so please take it just as a hint - development ist working on a “JDBC-light” driver that handles container managed transactions. Container managed persistence isn’t possible right now because, like you stated in your post, the whole thing is SQL-centric. Has to be done the old way through Tamino Java API and your own code.
Hope that helps a little,
Regards,
Johann
