请问高手如何处理邮件附件？我用JSP的setHeader方法来下载，可是文本文件时有问题啊？

==========================================================================String fileContentType=(String)hs.get("contentType");
InputStream in=(InputStream)hs.get("inputStream");
String attachmentName=(String)hs.get("attachmentName");

if(in!=null){
response.setContentType(fileContentType);
response.setHeader("Content-Disposition","attachment; filename=\"" +attachmentName+ "\"");
OutputStream outputStream = response.getOutputStream();
int c = in.read();
while(c != -1)
{
outputStream.write(c);
c = in.read();
}
}
==========================================================================
如果是文本文件时会出现找不到文件的错误。
谁能告诉我为什么会这样。

有没有更好的解决方法，最好有原代码.
Thinks in advance.

这个问题先结了吧！
中文的文件名处理要想一些办法，比如说，把文件名放在form中等。

搞定，我忘了close()了，但中文文件名时显示还是不正常，

高手啊，快来斑斑我啊!

敝人写的一个让浏览器下载文件的类的代码片断，看看合不合用。
/**下载一个文件

* @param contentType Content类型
* @param destFileName 目标文件
* @param blockSize 源文件
*功能：将一个文件数据发送给客户端下载
