RE: My JDBC does not work.
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)

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.
