该博客给出了JSP数据库连接的说明实例。代码中声明了相关对象，注册JDBC驱动，连接到MySQL数据库，创建驱动句柄，还展示了执行SQL语句的部分代码，最后关闭了结果集、语句和连接。

JSP数据库连接说明实例如下：
<%@page contentType="text/html;charset=gb2312"%>
<%
//声名
java.sql.Connection sqlConn;
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");
