因为ms word和excel的文档都支持html文本格式，因此可以先用word或excel做好模版，另存为Web页，然后将该html改成jsp，将数据部分动态填入即可，不用很辛苦的调整格式即可实现JSP打印报表。
word页面只要在jsp头设置如下指令：
< %@page contentType="application/msword;charset=GBK" %>
excel如下：
< %@page contentType="application/vnd.ms-excel;charset=GBK" %>
使用这种方式客户端必须安装有office软件，用户访问时将在ie中直接用word或excel打开该页面。
使用JSP打印报表的优势是模板设计、调整方便，无需在服务器端使用复杂的POI或jxl技术，也无需在客户端使用ActiveX控件技术，更安全、方便，轻松实现较好的打印效果。
JSP打印报表简单示例：
使用word建立一文档，画表格如下：
----------------------------
| 用户名 | 真实姓名 | 性别 |
----------------------------
| guest | 路人甲 | 男 |
----------------------------
保存为Web页test.htm， 将test.htm改名为test.jsp，修改其中guest、路人甲、男为从数据库动态查询，如下：
< %@ page contentType="application/msword;charset=GBK" %> < %@ page import="java.sql.*" %> < html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns="http://www.w3.org/TR/REC-html40"> < head> < meta http-equiv=Content-Type content="text/html;
