Hello Costin,

Yes, but when you run inside Tomcat, it's the only way :> I'd see this 
resolved the way that TM is set in Spring configurtion and its either 
JOTM or some TM taken from JNDI or something totally different... So you 
can enlist resources in your favorote TM just by using JTA API - then 
you don't have to create dummy Xid but relay on external TM 
implementation. Or am I missing something?

Cheers,

PS.
Could you set up some read only cvs to let more people review your work? 
I'm very curious about it and can't stand waiting :-)
