      jsp导出excel有很多种方法，在此介绍本人认为简单的一种，
前提：能在jsp页面取到要导出的内容，即 request能得到导出的数据，然后代码如下
<%@ page language="java" contentType="text/html;charset=gb2312"%>
<%@ page language="java"  import="java.util.*,
                                  org.apache.poi.hssf.usermodel.HSSFWorkbook,
                                  org.apache.poi.hssf.usermodel.HSSFSheet,
                                  org.apache.poi.hssf.usermodel.HSSFRow,
                                  org.apache.poi.hssf.usermodel.HSSFCell,
                                  java.text.DecimalFormat"%>
<%
    response.reset();
    response.setContentType("application/msexcel");
    response.setHeader("Content-disposition","inline;filename=untitled.xls");//定义文件名
    DecimalFormat f = new DecimalFormat("#,##0.00");
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("sheet1");
    String[] taxpayerid = request.getParameterValues("taxpayerid");
    String[] taxpayername = request.getParameterValues("taxpayername");
    String[] tax = request.getParameterValues("tax");
    String[] taxreduce = request.getParameterValues("taxreduce");
    String[] deratereasonname = request.getParameterValues("deratereasonname");
    String[] orgdeptname = request.getParameterValues("orgdeptname");
    String[] operatortime = request.getParameterValues("operatortime");
    String[] declaredate = request.getParameterValues("declaredate");
    String[] taxtermbegin = request.getParameterValues("taxtermbegin");
    String[] taxtermend = request.getParameterValues("taxtermend");

//以下以写表头
        //表头为第一行
      HSSFRow row = sheet.createRow((short) 0);
//定义10列
         HSSFCell cell1 = row.createCell((short) 0);

        cell10.setCellType(1);
//定义表头的内容
        cell1.setCellValue("纳税人管理码");

        cell3.setCellValue("税种");
        cell4.setCellValue("减免金额");
        cell5.setCellValue("减免原因");

        cell8.setCellValue("申报日期");
        cell9.setCellValue("所属期起");
        cell10.setCellValue("所属期止");


    for(int i= 0; i < taxpayerid.length; i++){
//定义数据从第二行开始       
  row = sheet.createRow((short) i+1);

        cell10.setCellValue(taxtermend[i].substring(0,16));
    }
    wb.write(response.getOutputStream());
    response.getOutputStream().flush();
    response.getOutputStream().close();

代码比较简单，首先把取得到的数据定义为一系列数组，然后定义表头，然后把取得的数据做为excel数据对应的放入，对poi有何疑问请参考http://java2.5341.com/3.html
