JSP中使用tag问题
不知道为什么 我javabean用不了 现在tag用起来也有问题了 先贴下代码<%@ page contentType="text/html; charset=GB2312" %>
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%@ taglib tagdir="/WEB-INF/tags" prefix="inquire"%>
<head>
<title>后台管理员</title>
<style type="text/css">
body
{
background-image:url(./images/fengjing.jpg);
background-repeat:no-repeat;
background-attachment:fixed;
background-position:center;
margin-top: 10%;
margin-right: 15%;
margin-bottom: 10%;
margin-left: 15%;
}
</style>
<html><body>
<div align="center"><FONT face=华文新魏 color=mediumslateblue size=6>
<h2>美食信息更新</h2>
</FONT></div>
<form action="newresult1.jsp" method=post>
<center><table>
<tr>
<td align="right"><FONT face=微软雅黑 color=lightskyblue size=5>请输入要更新的美食名称：</td><td align="left"><input type="text" name="foodname" style="width:180px;height:30px;"></td>
</tr>
<tr>
<td align="right"><FONT face=微软雅黑 color=lightskyblue size=5>请输入要更新的美食价格：</td><td align="left"><input type="text" name="price" style="width:180px;height:30px;"></td>
</tr>
<tr>
<td align="right"><FONT face=微软雅黑 color=lightskyblue size=5>请输入要更新的美食介绍：</td><td align="left"><textarea name="describe" rows=4 cols=30></textarea></td>
</tr>
</table>
<input type=submit name=submit value=提交更新 style="width:120px;height:30px;">
</center>
<br>菜单更新前的数据记录是：
<inquire:query dataSource="wsdc"tablename="Foods"user="zhujian"password="0951148"/>
<BR> <%=queryResult %>
</form></body></html>

求大神指点啊如果能在之后也帮下就好了 马上要催货了 急啊！！！！ JSP tag --------------------编程问答-------------------- 还有tag
<%@ tag pageEncoding="gb2312" %>
<%@ tag import="java.sql.*" %>
<%@ attribute name="dataSource" required="ture" %>

<%@ attribute name="password" required="ture" %>

<%@ variable name-given="queryResult" scope="AT_END" %>

现在打开来了 里面的显示对不上号 还有就是tag里面的话字体 颜色怎么修改 --------------------编程问答-------------------- 1、建议：不要用用标签，一般来说，标签是方便，同时带来问题就是自定义和扩展性不强，所以你还是要么ajax+jquery搞定，要么就自己写js。
2、建议：你的那个jsp写的太那个拉吧，jsp最好不要写成java程序，你真想那么搞，为什么不后台servlet把输出的table通过html输出就可以，这样很不规范！ --------------------编程问答-------------------- org.apache.jasper.JasperException: /newresult.jsp (line: 38, column: 49) The JSP specification requires that an attribute name is preceded by whitespace
JSP规范要求一个属性的名字是前面有空格,你仔细检查一下就明白！ --------------------编程问答--------------------
没学过JAVA了 做这个也不容易了 只要能运行 效果达到预期就行了 现在只要解决下面这个表格的显示问题了
补充：Java , Web 开发
