Hi all,
We have just started evaluating Cayenne for a multi-user Java Client
application.
We have hit the first wall, pessimistic locking. For some reason I have
been under the impression that Cayenne supports pessimistic locking but
somehow I cannot find any reference to it in the examples, FAQs or
JavaDocs, perhaps I am looking in the wrong place. Can someone point me
in the right direction?
The second question I have is about distribution of persistence across
a server client solution. Server talks to the data source and holds all
of business logic for the enterprise objects, clients communicate
exclusively with the server across the network and have only some of
the business logic for enterprise objects, mostly display and
validation logic. All pretty much al a Apple's EOF. We would like to
implement pessimistic locking on the server end.
Is this possible at present with Cayenne? If not, will this be possible
in the future? Finally, perhaps someone has already implemented this
functionality and would be prepared to share their work?
Your time is much appreciated.
Cheers,
Marek Wawrzyczny
software engineer
