Subject Re: Integration cayenne in Spring
Date Thu, 30 Jan 2014 16:40:03 GMT
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

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?
