Thanks for all your help. I was finally able to get the communication working by unchecking the SSLv3 Protocol in the configuration.

Here is what I am seeing in the log. Does this help?

Thanks for the reply

I am trying to populate an SSL\TLS configuration so that I can use it in SOAP business operation to call a third party web service.

They have also supplied me with CER and PEM files (instead of JKS) which I used to populate the configuration but I am getting ERROR #988: SSL handshake failed when I test the configuration.
