The problem with this approach is what do you do if the transaction
cannot commit (i.e. constraint violation) and you've already written
some data back to the response stream (you can't undo that)? That's
why it's better to bundle up all that you want to do into a service
method and call that under one transactional umbrella. Once that
completes, then you can go on and render the response.
