I think there is nor ClassNotFoundException

your exception is
IOException:
Connection refused(DESCRIPTION=(TMP=)(VSNNUM=168821762)(ERR=12505)(ERROR_STACK=
(ERROR=(CODE=12505)(EMFI=4))))

this means that the oracle server has refused connection.

Cause:
1. Oracle is not started.
2. Credentials are not correct.

Is there a way to specify the SSLContext for JDBC?
I don't want to do System.setProperty() for specifying my certificates.

Is there an alternate way of doing this?
