Re: Re: Re: Re: Distribued JOTM transaction between 2 jonasses

Benoit,

You said :

"JOTM does support the distributed transaction with multiples XA resources
(database + queue provider).
However it doesn't support nested transactions."

Do you mean JOTM is likely flat transaction model (because it does not
support nested transactions) ?

So i don't understand the purpose or comments :

# Set the Transaction Manager launching mode.
# If set to 'true', TM is remote: TM must be already launched in an other
JVM.
# If set to 'false', TM is local: TM is going to run into the same JVM
# than the jonas Server.

Or perhaps i didn't get the point.

Thanks for your advance.

Regards

Sontung
