JavaBean:jsp标签如果读取session中的值?

doBuy.jsp：<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<jsp:useBean id="orderInfo" class="com.cdjj.y2t066.entity.FoodOrderInfo" scope="session"></jsp:useBean>
<jsp:setProperty property="customerName" name="orderInfo" param="name"/>
<jsp:setProperty property="address" name="orderInfo" param="address"/>
<jsp:setProperty property="zipCode" name="orderInfo" param="code"/>
<jsp:setProperty property="telephone" name="orderInfo" param="phone"/>
<jsp:setProperty property="movePhone" name="orderInfo" param="mobile"/>
<jsp:setProperty property="notice" name="orderInfo" param="re"/><jsp:forward page="showOrder.jsp"></jsp:forward>
在showOrder.jsp中要读取orderInfo这个对象，我不知道该如何读取，请高手赐教...
