jatoolsprinter打印Jasperreport报表

昨天下了jasperreport的最新版本3.7.3看了下。弄了半天还是没能习惯他的报表制作方式。看了下他的打印是利用applet的来打印的。而且还需要客户端安装 十几MB的 jre 关于这个好坏，每个人都有自己的看法。今天我这里要说的是利用jatoolsprinter控件来打印jasperreport的报表。控件大小只有100k左右 关于jasperreport的报表制作这里不做说明，我是在环境中跑了下jasperreport的demo运行界面如下 运行JSP Example 如下图 下面我们对demo中的html.jsp进行修改 用jatoolsprinter来打印Jasperreport 的报表 蓝色部分为控件需要的内容 <%@ page contentType="text/html; charset=gb2312" language="java" %> <%@ page errorPage="error.jsp" %> <%@ page import="datasource.*" %> <%@ page import="net.sf.jasperreports.engine.*" %> <%@ page import="net.sf.jasperreports.engine.util.*" %> <%@ page import="net.sf.jasperreports.engine.export.*" %> <%@ page import="net.sf.jasperreports.j2ee.servlets.*" %> <%@ page import="java.util.*" %> <%@ page import="java.io.*" %>
