Trying to setup mySQL

[dwf2008]

Hi, total newbee here. I have installed android studio and followed a couple of simple lesson projects. Now I want to move up to a database project. I installed the current java connector for mySQL along with the workbench. Using the workbench I was able to construct a database and tables with some data. The tutorial I am following talks about importing a jar file which is supposed to be part of the mySQL archive, but I cannot find it anywhere on my pc. The tutorial is a few years old and I know things have changed. So is this jar file no longer needed? Can someone help me out here?

Also, it would be helpful if someone could point me to some more recent (current) tutorials.

Thanks
