下面接收上面表单中传过来的信息，并插入到mysql中
<%@ page language="java" contentType="text/html charset=gbk"
pageEncoding="gbk"%>
<%@ page import="java.sql.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

request.setCharacterEncoding("GBK")
int id = Integer.parseInt(request.getParameter("id"))
int rootid = Integer.parseInt(request.getParameter("rootid"))
String title = request.getParameter("title")
String cont = request.getParameter("cont").replaceAll("\n","<br/>")
Connection conn = null
Statement st = null
Class.forName("com.mysql.jdbc.Driver")
conn = DriverManager.getConnection("jdbc:mysql://localhost/bbs?user=root&password=690115399")
st = conn.createStatement()
conn.setAutoCommit(false)
String sql = "insert into article values(null,?,?,?,?,now(),0)"
PreparedStatement pstmt = conn.prepareStatement(sql)
pstmt.setInt(1,id)
pstmt.setInt(2,rootid)
pstmt.setString(3,title)
pstmt.setString(4,cont)
pstmt.executeUpdate()
st.executeUpdate("update article set isleaf = 1 where id = " + id)
conn.commit()
conn.setAutoCommit(true)
st.close()
pstmt.close()
conn.close()

当然最好的方法还是应该用jsp + JavaBean方式。
最简单的JSP页面中的数据库 *** 作方法：<%@ page
language="java"
contentType="text/htmlcharset=UTF-8"
pageEncoding="UTF-8"
%>
<%@page import="java.sql.*"%>
<center>
<H1><font color="blue" size="12">管理中心</font></H1>
<HR />
<table width="80%" border="1">
<tr>
<th>ID</th>
<th>书名</th>
<th>作者</th>
<th>价格</th>
<th>删除</th>
</tr>
<%
// 数据库的名字
String dbName = "zap"
// 登录数据库的用户名
String username = "sa"
// 登录数据库的密码
String password = "123"
// 数据库的IP地址，本机可以用 localhost 或者 127.0.0.1
String host = "127.0.0.1"
// 数据库的端口，一般不会修改，默认为1433
int port = 1433
String connectionUrl = "jdbc:sqlserver://" + host + ":" + port + "databaseName=" + dbName + "user=" + username

//

rs = stmt.executeQuery(SQL)
while (rs.next()) {
