我在第一个页面设了一列复选框，想通过勾选它传递参数到购物车页面，并在购物车页面显示出来。不知道是哪出错了，复选框勾选了以后以第二个购物车页面能且只能显示数据库里第一行信息，价格也没显示。这是为什么呢？恕我才疏学浅，很多东西弄不懂，希望各位指点一下：
我第一个页面的复选框代码是这样的：
<th scope="row"><input name="wares" type="checkbox" id="check" value="<%=list.WaresId%>">
购物车的代码是这样的：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@page import="java.util.*"%>
<jsp:useBean id="db" class="com.conndb" scope="session" />

<jsp:useBean id="list" class="com.WaresList" scope="session"/>
<jsp:useBean id="one" class="com.CartWares" scope="session"/>

if(wares!=null)
cart.setWares(wares);
