What transaction manager to use?

[Firas Adiler]

Hello,
 
There's a system which uses an embedded Geronimo as its transaction manager
(JNDI is off). I'm writing iBatis code which should operate on the same
database. The dabase and my code will run on the same machine, no
distribution is used.
 
My question is: Can I use SQLMap's transaction manager or should I call
Geronimo through JNDI?
 
Thanks for your time!
