Here is one possibility that comes to mind. Deploy your app exploded (). With the exploded
directory, have a directory (for example, csv) and place the generated file there, then
generate a web page with a link to the generated file: csv/tempfilename.csv. The user
clicks the link to get the file.
Another possibility is to, within your servlet, change the content type on the
ServletResponse to be "text/plain" (not sure if "text/csv" is valid,
you could try it) and set the response content to be the csv file contents.
