Yes.

What you are really asking is "how can I have an atomic conversation". Use @Begin(flushMode=MANUAL), and explicitly flush() when you want the changes to be persistent.

anonymous wrote : Isn't it that only in a non extended persistent context the transaction starts and ends with the mehtod invocation, whereas in an extended context the transaction lasts for the livetime of the SFSB?

Definitely not. Transactions held open across a user interaction are almost always a really bad idea.
