jsp原码如下：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@ page import="java.lang.Math.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<jsp:useBean id="newsconn" scope="page" class="news.newsconn"/>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
<style type="text/css">

</style>
</head>

<body>
<%
ResultSet rs=newsconn.executeQuery("select max(id) as maxid from news");
rs.next();
String max_id=rs.getString("maxid")+1;
rs.close();
String title=request.getParameter("tf1");
String author=request.getParameter("tf2");
String content=request.getParameter("ta");
/*String sql="insert into news values('"+max_id+"',";
sql+="'"request.getParameter("tf1")+"','"+request.getParameter("tf2")+"',";
sql+="date(),'"+request.getParameter("ta")+"')";*/
String sql="insert into news values('"+max_id+"',";
sql+="'"title+"','"+author+"',";
sql+="date(),'"+content+"')";
newsconn.executeQuery(sql);
out.println("<hr>");
out.println("<h2>添加新闻成功！</h2>");
out.println("<hr>");
%>
<p class="style1">请输入要添加新闻的详细信息！
</p>
<hr>

<form name="form1" method="post" action="newsadd.jsp">
<p align="center">标题：
<input name="tf1" type="text" size="90">

</form>
<p align="center"><a href="newsedit.jsp">编辑新闻</a> <a href="default.jsp">查看新闻</a></p>

多谢大家的热情帮助
按照showone的方法，问题已经解决啦，原来是不小心写少了个+号，：）

如果是form提交时的错误,那把你这个web应用的目录结构说一下,比如jsp的放置路径啥的,ok?

<%@ page import="java.lang.Math.*"%>这一句不要

<%@ page contentType="text/html; charset=gb2312" language="java"
import="java.sql.*,java.lang.Math.*" errorPage="" %>
使用insert语句啊
