I'm not sure what you mean with "external datasources" here. Do you mean an external database?

Jackrabbit (including all 1.3.x versions) already supports transactions with all database persistence managers. Note however that the underlying database needs to be under direct control of Jackrabbit, i.e. you must not use an external transaction manager on the data source that Jackrabbit uses.

Badal commented on JCR-1671:
----------------------------

I want to JackRabbit to work with external transaction manager. Jackrabbit should retrieve the connection through JNDI which is part of JTA transaction.
Any transaction done by JackRabbit will be part of global transaction and its commit/rollback will be decided by global transaction.

If this is not supported in 1.3, is this supported in any of the future releases?

Jukka Zitting resolved JCR-1671.
--------------------------------

    Resolution: Won't Fix
      Assignee: Jukka Zitting

You can make a Jackrabbit session a part of a managed transaction so there's no need (and it's in fact harmful) to manage the underlying database connection. See for example the jackrabbit-jca component where JCR sessions are automatically associated with a transaction manager.

Resolving this issue as Won't Fix.

----------------------------

Is there any documentation around managed transaction and any reference implementation details?

Not much. There are some related threads on the Jackrabbit mailing lists, you can find them by searching at http://jackrabbit.markmail.org/.
