When one should use XA Drivers ?

Hi all,
I have a question about the purpose of XA Drivers.
Time ago we had a bug in a transation processing application
that runs on Bea Weblogic 8.1 which doesn't use XA Drivers.

Because of that bug the application didn't rollback transactions in case of errors.

Since the ejb that controlled the tx is Container managed tx-Required, I was
told to investigate that the EJBException was correctly propagated to
the Container, and that was it.

So my question is: when are XA Drivers necessary ? only in Bean Managed tx ?
In CMT since it's the Container that drives the tx it's not necessary to use them ???

Thanks in advance

An XA driver is used when you have a transaction that spans more than one transacional resource. So if your EJB application performs data manipulation on two schemas for example you might use XA.
