Any quick way to determine if the communication is encrypted

I have a java process running on serverA on port 9200

It connects & communicates with the database on serverB port 4222.

Earlier I had not enabled encryption between them but now I have specified the java process on serverA to encryption communication by specifying the following on the java server

My OS is:

uname -a
-	SunOS mymac 5.10 Generic_150400-40 sun4v sparc sun4v

Is there is quick and easy way to confirm if the communication is now encrypted between the two parties ?

Code tags are the code button, not the quote button, not whatever you're hitting to get icode tags, but the code button, the one that says code on it,
