I'm kinda lost here, and SourceForge search is not working, so I have to
ask, and I'm sorry if this is a repeated question.
The thing is simple, I need a code snippet of how to use ResourceLink to
inatiate a file download.
There are probably simpler ways to do this, but what I did was to
Resource resource = new DownloadableFileResource(filename);
add(ResourceLink("fileLink", resource));
with my own class DownloadableFileResource (attached). I'd love to
hear better solutions, too.
