I\'ve followed the JDBC tutorial at: http://docs.oracle.com/javase/tutorial/jdbc/basics/gettingstarted.html, and managed to build and create my own JDBC database without too
I have been putting any needed jdbc driver at for example in the jre\lib\ext directory.
On my system that would be: X:\Java\jre1.8.0_181\lib\ext
Hope that helps.
