Background: I don't understand Datastore transactions.

Containermanaged transactions in an JEE application server,
makes it easy to write applications that have to
for example, withdraw money from an account,
and transfer into another account.

If the withdrawal works but the transfer crashes,
both withdrawal and eventual transfer changes are rolled back.


How would I handle this kind of scenario with the Datastore ?
Is it possible ? How ?
