Hi [~belaban]

 

I was trying to execute the demo chat application, In RHEL it worked even without passing udp.xml as input. But when i tried the same in Windows, It is not working. 

I am attaching udp.xml from v3.6.9 where there is no option to add bind_addr and mcast_addr. I tried adding it in udp.xml itself after mcast_port and it too didn't help.

Also I had one more question, How do we provide TCPPING list to this demo chat application?

 

I was going through one of your article and found another way to test to run mcast sender in one node and mcast receiver in another node. and this test passed in both rhel and win for me. 

*In Node1:*

java -cp jgroups-3.6.19.Final.jar org.jgroups.tests.McastSenderTest -bind_addr bdc-node1IP -mcast_addr 239.255.166.17 -port 49080 -ttl 9

*In Node2:*

java -cp jgroups-3.6.19.Final.jar org.jgroups.tests.McastReceiverTest -bind_addr bdc-node2IP -mcast_addr 239.255.166.17 -port 49080

 

Need your help in running demoChat application with the parameters you suggested. 

 

Thanks in Advance!.

 

Regards, 

Janardhan
