String mysqldriver = "org. gjt. Mm. MySQL. Driver"; // database driver
String mysqlurl = "JDBC: mysql: // localhost: 3306/BBS? Useunicode = true & characterencoding = gb2312 "; // database connection string
String mysqluser = "root"; // database username
String mysqlpsw = ""; // Database Password

Class. forname ("org. gjt. Mm. MySQL. Driver"). newinstance (); // register the driver
Conn = drivermanager. getconnection (mysqlurl, mysqluser, mysqlpsw); // get the connection

2. Request object settings:
<% Request. setcharacterencoding ("gb2312"); %>
