Transaction management for multiple database Using Spring & Hibernate

Question

Am coming up with a Spring & Hibernate application which has Inserts/Update to its own system database and it even has to Insert/update other systems with different data

Answer 1

This will need to be done by the container where your application runs (e.g. JBoss App Server) or you'll need to hook into some other transaction manager such as Bitronix. Out of the box in a JavaSE application, you'll only get a "best-effort" attempt at managing a transaction between multiple datasources.

You'll need to define connections to both databases using an XA driver and then make sure your transaction manager is leveraging a two-phase commit.
