Thanks for your advices. After I modified my code according to your advice i get following error message.
Invalid authorization specification: Access denied for user: 'jianping@chambleea' (Using password: YES) java.sql.SQLException: Invalid authorization specification: Access denied for user: 'jianping@chambleea' (Using password: YES) at org.gjt.mm.mysql.MysqlIO.init(MysqlIO.java:330) at org.gjt.mm.mysql.Connection.connectionInit(Connection.java:261) at org.gjt.mm.mysql.jdbc2.Connection.connectionInit(Connection.java:89) at org.gjt.mm.mysql.Driver.connect(Driver.java:167) at java.sql.DriverManager.getConnection(DriverManager.java:517) at java.sql.DriverManager.getConnection(DriverManager.java:199) at StocksMy.main(StocksMy.java:66) I am just wondering, I do have a account 'jianping' which have all privilege in global level. I will be appreciated for any further advice.
