如何实现将统计表格保存成excel文件

Java,jsp,javascript中如何实现将统计表格保存成Excel文件？
---------------------------------------------------------------
&lt SCRIPT LANGUAGE="JavaScript" &gt
function AutomateExcel()
{
var i,j;
// Start Excel and get Application object.
var oXL = new ActiveXObject("Excel.Application");

oXL.Visible = true;

// Get a new workbook.
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;

// Add table headers going cell by cell.
// tblout表的ID
for(i=0;i&lt tblout.rows.length;i++)
for(j=0;j&lt tblout.rows(i).cells.length;j++)
oSheet.Cells(i+1, j+1).Value = tblout.rows(i).cells(j).innerText

oXL.Visible = true;
oXL.UserControl = true;
}
&lt /SCRIPT &gt
//这个问题其实你搜一下就有了

首先你的页面上要有一个按钮：save
这个按钮先做查询数据库，然后action转到保存excell的页面，即我给你的这些代码，由于我的是用这个页面是隐藏的，点击save时有跳出界面问你是打开还是保存，xxxxxxxxxxxxxx是你调用数据库的记录，
&lt %@ page contentType="text/Html;charset=gb2312" % &gt
&lt %@ page import="java.lang.*"% &gt

try{
response.setContentType("Application/msexcel");
response.setHeader("Content-Disposition", "attachment;filename=trainlist.xls");
StringBuffer cont=new StringBuffer("");
