Tomcat 6 + Jackrabbit + transactions

[Tony Rozga]

Hi,  Jackrabbit newb here:

I've found plenty of examples/mail threads that talk about deploying 
Jackrabbit as a JCA resource and how that means Jackrabbit is 
automatically aware of the JCA transactional context.  We need to 
support Tomcat 6 though and that config still confuses me as Tomcat is 
not a JCA container.

I've found several transaction manager implementations (Bitronix, 
Atomikos) that can be used in Tomcat.  If I setup on of these and start 
a UserTransaction in my code and then do some Jackrabbit ops, will 
Jackrabbit be aware of that transaction context?  Given that a 
Jackrabbit Session is the underlying XAResource, what about a single 
transaction that spans multiple Sessions?

Thanks,
Tony Rozga
