I have a JSP file which creates an Excel document.
I want to dynamically set the name of the file to be downloaded.
This is how I set the file name to "test.xsl":
<% response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=" + "test.xsl" );
%>
How can I set the file name to be test-${today's date}.xsl ( i.e. test-20100805.xsl ) ?
String fname = MessageFormat.format(
"test-{0,date,yyyyMMdd}.xsl", new Object [] { new Date() } );
response.setHeader("Content-Disposition","attachment; filename=" + fname );
I think this should work for you.
The text in the braces tells the MessageFormat
class to insert value 0
from the given array, format it as a date
using the format yyyyMMdd
(e.g. 20161231
for Dec 31st 2016).
