I am sorry if it is out of topic. I posted it on JDBC board, but that board does not have much traffic.

You would need to use a 2-Phase Commit to manage this. The gotcha for 2-PC is that your JDBC Driver and J2EE Application Server must both support them. If you fit both of these requirements then it is actually pretty easy.

Good answer Chris. He is right to do that you must be able to do two phase commits. I believe some App Servers have this, and some haven't implemented it yet.
