#1Apache Derby is added into main. create table should only execute once(we dont create new db every time). in order to make db working: click Service tag, javadb create db (not really create, all we need is select the directory for the db). then the ChessHitsUserDB should appear, then run the main test it.. let me know if there is any error. #2altered ChessHits class to load db. #3 added new class for the db which will have all the necessary sql function for the game
