This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
When we have a two-phase commit process, all the participants must successfully complete the transaction. In such a case can the individual participants, have their own transaction context - a UserTransaction context for instance.
