Hi,

I am writing a servlet which output some text. When user call this
servlet, it display the content of the text in the web browser. But
this is not what I want. What I really want is once user call this
servlet, a window popup with options of "Open", "Save", and "Cancel",
just like you download someting from the web.

How can I do it?

Thanks,

ff

Assuming what you want is sending a text file instead of rendering
markup on the browser, then look at writing on the response, and
setting response headers and type.

Something like:

response.setContentType("text/plain");
response.setHeader("Content-Disposition","attachment; filename=" +
yourFileName);
response.getWriter().write(textContent);

Thanks, it worked very well. I found, however, if I added:

response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");

it would not work. Do you know why?

Thanks,
