As the author of Tyrex plugin, I have to advise you not to use Tyrex 
plugin in production environments, it is very inefficient (for every 
outstanding (not committed) transaction and its distributed XAResource 
(or propagated tx) you get an instance of an RMI UnicastRemoteServer 
running). More efficient implementation is possible (I can share some 
design ideas and some code if someone is willing to do the complete 
implementation).

On the other hand, distributed 2pc is slow to begin with. If you are not 
doing lots of it, it might still be fine. Please, avoid distributed 2pc 
as plaque, if you need performance.
