Serve file without download links etc
I need to implement public URLs that lead directly to files. I'm
thinking I could create a page that takes a unique file identifier as
parameter, uses that to look up the file, and serve the file. But how
can I serve the file immediately without using download links etc?

Ended up doing something like this:
//in Application init
mountResource("file", new ResourceReference() {
@Override
public IResource getResource() {
return new AbstractResource() {
@Override
protected ResourceResponse newResourceResponse(Attributes
attributes) {
final FileDescription fileDescription =
fileDescriptionService.findOne(attributes.getParameters().get("file").toLong());
final AbstractResource.ResourceResponse resourceResponse
= new AbstractResource.ResourceResponse();
resourceResponse.setContentType(fileDescription.getMimeType());
resourceResponse.setContentLength(fileDescription.getSize());
resourceResponse.setFileName(fileDescription.getName());
if (resourceResponse.dataNeedsToBeWritten(attributes)) {
resourceResponse.setWriteCallback(new
AbstractResource.WriteCallback() {
@Override
public void writeData(Attributes attributes)
throws IOException {
try (InputStream data =
fileDescription.getData()) {
IOUtils.copy(data,
attributes.getResponse().getOutputStream());
}
}
});
}
return resourceResponse;
}
};
}
});

Mount a recourse?

You will need to trigger some kind of request to the server in order to be
able to download a file. See
https://cwiki.apache.org/confluence/display/WICKET/AJAX+update+and+file+download+in+one+blow
for an alternative to download link.
