There should be code that says DriverManager.getConnection(...). Can you also paste that code? –WillShackleford Aug 14 '15 at 21:15 Here it is: i60.tinypic.com/33ufvrt.png –Achraff-Nour MESKI Aug 14 '15 at 21:47 I've used this url "jdbc:derby://localhost:1527/Suppliers;create=true" with username and password "root".
