1.JavaMail中关于收取附件的问题

用JavaMail收取附件时，我把附件的输入流读到了，但我不想把这个轮作输入流输出到文件中，而是做一个链接，点一下这个链接就用IE打开这个附件(如果IE打得开就在IE中打开，如果找不开就会提示你保存)，但我实现不了。有哪位大侠知道帮帮忙，感激不尽!!!!!

你做的是web的程序吗?
如果是,给出一个链接给用户,让他点击的时候发出请求,你的控制程序得到请求后再去把输入流写到response输出流,这样用户就得到这个文件.

类似代码:
response.setContentType(abcType);
InputStream input = abc.getInputStream();

byte[] buffer=new byte[input.available()];
input.read(mBuffer);
input.close();

OutputStream out = response.getOutputStream();
out.write(mBuffer);
out.close();

注意abc是你的代码

谢谢qunrose，现在这个附件可以保存了，但是还有一个问题，就是我保存附件的时候，弹出的保存对话框中的文件名并不是附件的名字，而是显示附件内容的页面的名字（如listAttachment.jsp）。
问题二、一般情况下，IE可以浏览的附件就会直接在IE里打开（如html文件和文本文件），但我这里不会。
大侠帮忙！

you can set the HTTP header "Content-Disposition" to set the filename
explicitly in the Save As dialog.
For me, I have been used the value:
"inline; filename=<your file name>.zip".
I knew that people set the value as:
"attachment; filename=<your file name>.zip".

however, I don't know the different between "inline" and "attachment".
Anyway, you can have a try.

在准备好output stream后，写数据信前，加上以下代码：
response.setContentType("text/txt");//for question 2
response.setHeader("Content-disposition", "attachment; filename=" + fileName);// for question 1
