Thanks a lot for the prompt feedback, Guillaume!

Is it correct, that the existence of a JCA flow is not mandatory for using the JMS JCA processors, i.e. we can still use our SMX3 JMS JCA endpoints in SMX4? Am I correct, that, if I'd like to have the same behavior with the new SMX4 JMS endpoints, I would have to set the "transacted" property to "xa"? > >> Currently the OSGi spec does not include transaction handling, right?

In our EAI scenario we leverage some JEE services in our SMX3 platform: JCA, JTS/JTA, clustered JMS, clustered cache, JNDI, etc.. So I am thinking of ways, how to achieve this with SMX4. It doesn't seem that easy to host an OSGi container in a JEE app server and use the app server's infrastructure services, since the class loading requirements seem to be not really compatible. Also, we don't want to limit ourselves to one and only one transaction manager. So, what can we do if we would like to exchange the Geronimo transaction manager with some other implementation? Do you have any hints, how we could integrate our enterprise level cross cutting services with SMX4? Is it possible with SMX4? Or do we have to wait for the first enterprise OSGi specs and their implementations to come out? >> Questions over questions. ;-) >> >> Any help would be greatly appreciated! >> >> Cheers >> >> Oliver >> >> >> >> -- >> View this message in context: >> http://www.nabble.com/How-does-SMX4-transaction-handling-if-it-runs-in-an-OSGi-container--tp20973338p20973338.html >> Sent from the ServiceMix - User mailing list archive at Nabble.com. >> >> > > > > -- > Cheers, > Guillaume Nodet > ------------------------ > Blog: http://gnodet.blogspot.com/ > ------------------------ > Open Source SOA > http://fusesource.com > > Again, thanks a lot in advance for any insight!
