Integration cayenne in Spring
Hi,
I done a spring integration of cayenne 3.0.2 ( JTA Support and Transaction Proxy,override default configuration in xml,...),
and now I will migrate to 3.2. I have supposed implement TransactionManager Interface but it's never used.
my question is: Are you plan to integrate TransactionManager interface in DataDomain class to replace runInTransaction() method ?
Best regards,
Christophe Friederich

Hi Andrus,
Thank you for the reply.
I'm investigating the feasibility. My first problem is the transaction transparent synchronization for more than one transaction (multiple database) during one transaction invocation. Second, the possible conflict with my own transaction status and the status of Cayenne Transaction class (always if multiple database). But for my project, that's the icing on the cake.
Best Regards,
Christophe Friederich

Is that not working for you?

Hi Christophe,
while it is actually a good idea to reuse TransactionManager inside Cayenne (I am totally open to doing it), a “standard” solution was to tell Cayenne to use “external” transactions, which simply skips the commit inside Cayenne, delegating that to the external code that manages the DataSource. Is that not working for you?
Cheers,
