G’day Joshy, Depends how the server implements the “local” binding - again you’re into proprietary extension land at that point.

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?

In contrast CMIS is far less less platform dependent and is designed primarily for “out of process” clients, both of which makes this kind of thing a fair bit more complex. As I mentioned below, it would be technically possible for a given CMIS server to support this kind of thing as a proprietary extension, but I don’t know of any servers that have done so. It would probably involve something nasty like X/Open XA< http://pubs.opengroup.org/onlinepubs/009680699/toc.pdf> or similar, since you’re effectively managing distributed transactions at that point. I, for one, welcome our new stateless-favouring overlords. ;-) Cheers, Peter On 2014-10-30, at 7:42 AM, Joshy Augustine <joshymaugust...@gmail.com<mailto:joshymaugust...@gmail.com> <mailto:joshymaugust...@gmail.com>> wrote: Thanks Peter. I was just considering the possibility of replacing a JSR 170 Compliant Repository with a CMIS Compliant one. From the documentation, it looks like JSR 170 Repository could potentially support transactions.

I have no idea if any current servers offer this however (Alfresco doesn’t, for example). Interesting point of note - the 1.1 spec doesn’t even state whether individual services are atomic or not. It seems to be implied that they are (e.g. in sections 2.2.4.14 and 2.2.4.17), and I believe most current servers are implemented that way, but it was interesting to me that that isn’t explicitly defined anywhere.

Does anyone know if CMIS Specification mentions about Transactions? For example, is there any possibility for a CMIS Repository API Invocation to participate in a transaction started by the client of the API? Thanks, Joshy -- Cheers, Josh -- Cheers, Josh
