There are serveral ways to deal with them.
1. Interaction without regard to transactionality. This approach is appropriate when there is no need for transaction management.
2. Development of transactional interfaces. This approach is the most comprehensive, but also the most time consuming because it needs to implement JTA interfaces (implementation of javax.transaction.xa.XAResource).
3. Implement the interactions in a “pseudo-transaction” that explicitly checks for and manages error conditions and rollback. I thought this approach like transaction in the web service which have to implement method for rollback by yourself.
In the detail, you can read at TheServerSide.
