Hi Kishore, Thank or your quick answer, Vinayak sugestion partly worked for me... I said `partly` because the messaging still not working as expected (note: probably I'm doing something wrong here!). Here are some snippets of my own code: http://pastebin.com/SGfVJrUD
Regarding contribution... today we're in a rush to release, but after it... I plan start to work on Infinispan backend ;) Cheers, --- Alexandre Porcelli [email protected] On May 2, 2013, at 1:18 PM, kishore g <[email protected]> wrote: > Hi Alexandre, > > Glad you like Helix. > > 1.
