To set the download file name, in addition to the "text/csv" mime type
(which you already have set), write the following java code in your
Action or (if necessary) as Java in your JSP:
response.setHeader("Content-disposition", "attachment; filename=" +
CSV_FILE_NAME);
where CSV_FILE_NAME is the name you want the user to see for the csv
file.
Since this is a dynamically generated file, if you're using https and
need to work in IE you may also want to set the following:
response.setHeader("Cache-Control", "max-age=0");
response.setHeader("Pragma", "public");
see the following two links for more details:

Subject: Downloading file rendered in JSP
Hi,
I'm trying to make one of my pages downloadable as a CSV file.
Currently my XML is configured like this:
<action name="downloadCSV" class="test.struts.ListItems"
method="downloadCSV">
<interceptor-ref name="standardStack"/>
<result name="success">/pages/download.jsp</result>
</action>
And /pages/download.jsp renders the list as a CSV.
I have changed the content type in the CSV:
<%@ page contentType="text/csv" %>
But I'd like to force the contentDisposition so that I can control the
filename.
I know it's easy to do that using StreamResult, but that doesn't look
like the right solution for me, since I don't want to access a file on
the file system and return it, but rather offer a page rendered by that
JSP as downloadable.
Is there any way to do this, or a way to use StreamResult and configure
it so that it can work with a page rendered by a JSP?
Thanks
D.
