Yes, there is a XA interface for ozone. I used Tyrex for the development but
I'm not sure if I did it right, even after many emails from Assaf of ExOffice
;) Also, you will probably have to add/change some small things to get it
working, especially integration with JNDI, which is needed for Tyrex, is
missing. I'm very interested in real-world experiences here, so please send me
your questions and I will try to help.
