Subject Re: CMIS and Transactions
Date Fri, 31 Oct 2014 16:45:34 GMT
Thanks again Peter.

While going through Open CMIS Documentation, I came across references to a
non-standard 'Local' Binding provided by Open CMIS Framework. My
understanding is that this is a binding that can be used to invoke a CMIS
Server running in the same JVM. If one were to target a new/existing  Open
CMIS based CMIS Server Implementation over a 'Local' binding, is it
possible that it can participate in the transaction started by the client?

Thanks,
Joshy
