At a minimum, we need to obtain a TransactionManager (easy) and define XAResource implementations for each resource participating in the transaction (easy for messaging, not as easy for db). In ruby, the activerecord jdbc adapter helps us with the latter, allowing us to automatically create XAResource's for each key listed in the Rails database.yml file, using standard ruby conventions to provide XA "for free" when a rails app is deployed under TorqueBox. We need to figure out what those conventions are for clojure. Or help define them. Also, the Java API's for XA are kinda awkward. I hope we can wrap them a bit to make the common usage patterns simple.
