I have requirement where a CSV file needs to created and opened up in new window to be downloaded. I using CSVPrinter to create the file. Please help me on how to make the portlet show the file in anew window.
You could probably just set the mime type to CSV or XLS, and when the client clicks on the link, they get the file. Would probably be even easier if the file was saved to a web server, and a non-portal link was provided to the resource. Portal links always get so messed up.
