Displaytag 不输出数据，后台可以接收action传的数据。

Displaytag分页感觉很方便，但是还没输出来，下面是代码：
struts.xml 配置

<!-- 查找书籍 -->

     <action name="findbook" class="com.action.FindBookAction" method="excute">

     <result name="success">/normal/findbookresult.jsp</result>

     <result name="fail">/actionfail.jsp</result>

     </action>

下面是com.action.FindBookAction中查询结果result 放到books里的

ActionContext.getContext().put("books",result);

下面是界面JSP代码了

<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>



<%@ taglib uri="http://displaytag.sf.net/el" prefix="display" %>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
