Here is the home of the 2.1.x and earlier version of BTM. If you're looking for the latest version, you should go have a look on GitHub.
BTM 2.1.x is now in maintenance mode and only critical bug fixes are considered. Any new development is now happening in the 3.0.x version.
The Bitronix Transaction Manager (BTM) is a simple but complete implementation of the JTA 1.1 API. It is a fully working XA transaction manager that provides all services required by the JTA API while trying to keep the code as simple as possible for easier understanding of the XA semantics.
This is BTM's strongest point compared to its competitors: it is trivial to configure and when something goes wrong it is much easier to figure out what to do thanks to the great care placed in useful error reporting and logging.
