Which server? As I understand it Postgres-XC can have multiple clusters
in use, so I am still not sure which one you are connecting to?

To make things easier to debug, use explicit options. The above command
leaves a lot to env variables and hidden configuration. There is a good
chance you are not connecting the way you think you are.

At this point do none of the Tomcat/JDBC process . Until you solve the
above, it just gets you to the same error and it confuses the issue.

The first thing to solve is why you are getting two different error
messages, in particular why it says SSL is off. The second is whether
the user and database specified in the error are who are trying to
connect as and the database you are trying to connect to.

Also have you gone through Table 17-3. SSL Server File Usage at link
below to see if everything is in place:
http://www.postgresql.org/docs/9.2/interactive/ssl-tcp.html

Have you followed Rays suggestion:

'I use openssl to verify the chain, I think that would help you know
what's going on:

openssl verify -CAfile rootca.crt  user.crt
