问了好几天了怎么没人帮加解决一下jspSmartUpload下载时的乱码问题

Question

晕，有这样提问的吗？？jspSmartUpload我前两天才做了上传，下载，处理中文问题，
你说你的情况，

Answer 1

to dkmilk(迪克牛奶____来一杯？) :
不知你做下载时有没有试过下载XML文件的情况！我的代码如下：
<%@ page contentType="text/html;charset=gb2312" import="com.jspsmart.upload.*" %>
<%
// response.sendRedirect("/upload/yuehai.rar");
// out.print("您忆经下载成功！"); String xmlFile = "/xmlfile/idenfee/wsq1.xml";
// xmlFile = "/xmlfile/idenfee/aaa.xml";

// 新建一个SmartUpload对象
SmartUpload su = new SmartUpload();
// 初始化
su.initialize(pageContext);
// 设定contentDisposition为null以禁止浏览器自动打开文件，
//保证点击链接后是下载文件。若不设定，则下载的文件扩展名为
//doc时，浏览器将自动用word打开它。扩展名为pdf时，
//浏览器将用acrobat打开。
su.setContentDisposition(null);
// 下载文件
%>
<script language="javascript">
// alert("<%=xmlFile%>");
</script>
<%
// su.downloadFile(xmlFile); su.downloadFile(xmlFile,"xml","idenfee.xml");
%>
当wsq1.xml有n条记录即足够大（多大？还没有找准），才能下载，好果形如：
<?xml version="1.0" encoding="gbk"?>
