Cause:

Incompatibility of authentication protocol used by old client for connecting to higher version databases like oracle 12c or 19c.





Solution:

Download ojdbc6.jar (which is Certified with JDK8, JDK7, and JDK) from below oracle website and replace the existing oracle jdbc jar file environment declaration with ojdbc6.jar location of library & re-run program.


Download ojdbc drivers

#environment declaration
JAR=..:../lib/ojdbc6.jar
