Subject Re: Using JTA and Jackrabbit

The standard Jackrabbit Session is an XASession which implements an XAResource which you can
attach to Global transaction.

    XASession xasession = (XASession) session;
    Transaction transaction = transactionManager.getTransaction();
      if (transaction != null) {

from that point on the XASession will respond to the transaction lifecycle of the transaction.
IIRC, nothing is visible to other threads, the shared item manager or the persistence manager
until transaction.commit() happens, even if sesison.save() happend before then.
