Thanks,
I was able to convert a DownloadLink to a ResourceLink (backed by a byte[]),
BUT that changed the behavior of the link.
Previously, all clicks on the DownloadLink would result in a Open / Save As
dialog box. This is what we want. The file type is MS Excel, and it was
offering to open or save the file.
Now, with the ResourceLink, it's a little different:
1) The Excel file opens immediately inside of IE, no prompts
2) If, from another browser/session, the link is clicked by another user,
there's an Excel error, "A document with the name 'localhost' is already
open"
The code:
ByteArrayResource bar = new ByteArrayResource("application/vnd.ms-excel",
generateExcelBytes()); //returns byte[]
ResourceLink exportLink = new ResourceLink("exportLink", bar);
add(exportLink);
Previously, with the DownloadLink, the code was:
DownloadLink exportLink = new DownloadLink("exportLink",
generateExcelFile()); //returns File
add(exportLink);
