We're modernising an existing enterprise Java application that relies on XA. It is a message oriented architecture and we're finding race conditions are occurring sporadically. We receive a message into a Message Driven Bean, interact with the database and then fire off another message to another MDB that expects data to be in the DB, however because it's not all wrapped up in one transaction the data isn't there when the second MDB starts processing, so it blows up.
