[jgroups-users] JGroups SimpleChat - not working - Need help

Hi Bela,

Thank you so much, your replies to users questions are awesome. But mine is
something different, which I couldn't able to figure it out. It would be of
great help if you could throw some light on this.

We are using JGroups v3.6.10.Final & ehcache-jgroupsreplication v1.7 with 2
nodes. Ours is a Mobile chat application using WebSocket.
Each node is configuired for 2 different URLs like cluster01.xxxx.xxxx &
cluster02.xxxx.xxxx. 
The chat app is installed in 2 different mobiles one is pointing to 01 &
other is pointing to 02. The chat messages are not getting replicated. I
also tried the SampleChat.java even this is not replicating, please can you
suggest the what would be the reason.
