我写了如写的购物车代码:
<html>
<head>
<title>添加购物车</title>
</head>
<style type="text/css">
<body bgcolor="#FFFFFF">
<%@ page import="java.sql.*"%>
<%@ page import="java.util.*"%>
<jsp:useBean id="conn" scope="page" class="myshop.conn"/>
<%@ page import="buylist.buylist"%>
<%
String ISBN=request.getParameter("isbn");
String TITLE="";
String PRICE="";
String sql="select TITLE,PRICE from bookinfo where ISBN='"+ISBN+"'";
ResultSet rs=conn.executeQuery(sql);
if(rs.next())
{TITLE=rs.getString("TITLE");
PRICE=rs.getString("PRICE");
}
buylist mylist=new buylist();
mylist.TITLE=TITLE;
mylist.ISBN=ISBN;
mylist.number=1;
boolean listFlag=true;
Vector shop=(Vector)session.getValue("shop");
if(shop==null)
{shop=new Vector();
}
else
{
for(int i=0;i<shop.size();i++)
{buylist list=(buylist)shop.elementAt(i);
if(list.ISBN==mylist.ISBN)
{list.number++;
shop.setElementAt(list,i);
listFlag=false;
}
}
}
if(listFlag)shop.addElement(mylist);
session.putValue("shop".shop);
rs.close();
%>
<br><font size="4" color="#FF0033">您选购的书籍已经成功的添加到购物车中！</font></b><br>
<br>
<a href="JaavaScript:window.close()">关闭窗口</a>
<a href="list.jsp target="_blank" onclick="javaScript:window.close()">查看购物车
</a></div>
</body>
</html>
运行后显示如下错误:shop cannot be resolved or is not a field
希望有哪位厉害点或者不是很厉害但是看得出哪里错了的能够给小弟一个解答,在这里先谢了.
