Good question :).

Agreed. It'd be nice to have a test application, packaged in an EAR for
example, that would exercise all the unusual scenarios including
recovery. It'd be extremely useful for testing JTA implementations as
well. Sun might actually have a test kit like that, but they're probably
proprietary and expensive.

Interesting. I don't know Hibernate very well, but I'd assume that it's
just using the UserTransaction et al. APIs, and shouldn't look any
different than other applications to the JDBC driver.
