RE: Sandesha in a Cluster

[Alex Horwitz <AH...@midwestiso.org>]

Sorry to come back to this after so long (was far away, unexectedly), but I would definitely be interested in whatever you developed Chathura, only for some basic scalability testing.  Would it be possible to shared this code?

Thanks for your help.

Alex

That is great. Chamikara is working on Sandesha2's persistence layer and we 
have some issues with licenses
Can we use this under Apache? I mean IU has some licence for all the stuff. 
So if we can use this under apache then we can use it to implement the 
persistance queues.

Jaliya,
There is a persistant Queue implementation developped at IU, may be
you guys can use it if you are interested. I am not sure it meets your
requirements, i can show it to you offline, if you are interested . We
use it for messaging Queuing in the WS-Messenger broker.
 Don't think there will be any Licensing issue, lets not worry abt it for 
now.
Thanks
Chathura
