Hi i am not an expert in java. but trying to give a solution.

you can have a superclass where all the connection related stuff happens and any other base class where you can extend and use it.

Later any switch in your DB for specific 3rd party drivers you can rewrite the superclass.

Again I am no expert. Just trying around here to learn. :)
