   java.sql.Statement sqlStmt;
   java.sql.ResultSet sqlRst;
   //regiester jdbc driver


   String DBUser="d12345";
   String DBPassword="12345678";
   String DBServer="s509.now.net.cn"; // Can't use localhost , you must use IP or CNAME
   String DBNAME="db_abc_com"; // change to your db name

   Class.forName("org.gjt.mm.mysql.Driver").newInstance();
   //connect to the database
   sqlConn=java.sql.DriverManager.getConnection
   ("jdbc:mysql://"+DBServer+":3306/"+DBNAME+"?useUnicode=true&characterEncoding=gb2312", DBUser,DBPassword);
   //create the driver handle
   sqlStmt=sqlConn.createStatement(java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE,java.sql.ResultSet.CONCUR_READ_ONLY);
   //excute sql
   //sqlRst=sqlStmt.executeQuery("select * from test");
