That is correct. Why are you using two different database resources to access the same resource anyway?

If you are using only one database resource (only one oracle database for example) you needn't XA. you can use local jdbc transaction with spring. see http://static.springframework.org/spring/docs/2.0.x/reference/transactio n.html for more details greetings martin Armeanu, Christian wrotes: I don't know about the transaction support with iBATIS DAO, but if you could the recommended Spring DAO for example. All you would need to do is to configure the appropriate transaction manager.

Do I need to use a different Oracle library, or configure this differently? I'm not an XA expert...

They share the same runtime user information).

I'm using Oracle 9.2 client libraries, and this is with iBATIS-2.2.0. Here's my code pattern--I have two Daos involved--one "Foo" and one "Bar". I'm transacting Foo here. (I've tried transacting both and get the same result, too--so it seems to be relating to the FooDao transaction somehow) DaoManager dm = FooDaoManager.getDaoManager(); try { dm.startTransaction(); op1UsingFooDao(); logger.info("1"); op2UsingFooDao(); logger.info("2"); op3UsingBarDao(); //throws SQLException when the Tx code is off, hangs here when using Tx logger.info("3"); //never gets here... dm.commitTransaction(); } finally { logger.info("Inside finally block"); dm.endTransaction(); } Output with no transaction code (application terminates): 1 2 Inside finally block Output with transaction code present (application hangs): 1 2 I expected that the transaction would roll back when an exception was encountered by triggering the finally code. However, since it hangs, I don't know where or why it hung in op3UsingBarDao()...? What am I doing wrong in this scenario and how should I correctly address this? This scenario is consistent with the documentation, but the docs don't cover multiple DaoManager transactions... Thanks, -Dave
