 <p>Thank you, all commentors and visitors, especially @PM 77-1, I solved the problem with your help, </p> <p>generally speaking, I need three things to initialize my JDBC tutorial, 1.MySQL 2.Eclipse and a nice plugin as an option 3.JDBC driver, for me it is mysql driver mysql.com/products/connector</p> <p>use the @PM 77-1 provided tutorial to set up the project to manipulate the database. </p> <p>But if you need a database GUI in Eclipse like me, you will need a plugin like DBview, my initial one database explorer is no longer in Eclipse. And remember to download the JDBC driver with .jar as the end. It can be find at platform independent version. </p> <p>Ok that's all.</p>
