Hi Rajini Thank you very much. It perfectly works.
I think in my setup I was trying to use a CA (certificate authority) to sign the certificates from client and server, and then adding it to trust store and keystore. I think in that process, I may have messed something. I will try above config with a CA to sign certificates. Hopefully that would work too. Thanks a lot again.
