Is there an easy way of overloading the ContentDisposition.ATTACHMENT already used in DownloadLink? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Download-serves-empty-files-with-correct-number-of-pages-tp4670117p4670127.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

OK so the empty PDFs where due to some strangeness with the build config which is fixed. The filename and extensions are added by item.getModelObject().getFile(). So it works fine now however using DownloadLink the file still downloads rather than is opened in a new tab.

'hc' has no extension. Neither the server, nor the browser will have idea
how to present it. So I think it is expected that the browser downloads it
instead of showing it in a tab/window.

"correct number of pages"
I'd say the correct file is delivered. It is your viewer that doesn't
represent it correctly.
Check the sizes of the original file and the downloaded one.
I guess the file is binary so also try with 'cmp' (Linux command line) or
something similar.

Re: Download serves empty files with correct number of pages !?!
I was using the AjaxDownload outlined in
https://cwiki.apache.org/confluence/display/WICKET/AJAX+update+and+file+download+in+one+blow
before with the same problem.
I switched to DownloadLink :
IModel model = new LoadableDetachableModel() {
@Override
protected File load() {
File path;
try {
path = new ClassPathResource("descriptors/hc").getFile();
} catch (IOException exception) {
return null;
}
return new File(path, item.getModelObject().getFile());
}
};
add(new DownloadLink(ID_ALARM, model) {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.getAttributes().put("target", "_blank");
}
});
Now the file downloads rather than opening in a new tab and it's still blank
with the correct number of pages...

Nope. By the time we get to the line :
return new FileResourceStream(new File(path, getModelObject().getFile()));
the path isn't null and this ends up instantiating a FileResourceStream with
a file that both has the correct path and exist()s...

Hi,
Why don't you use DownloadLink or ResourceLink ?
At least check their sources for inspiration.

path = new ClassPathResource("descriptors/hc").getFile();
the path isn't null ?

Re: Download serves empty files with correct number of pages !?!
printing the exception could help
} catch (IOException exception) {
return null;
--> print stack
}

Download serves empty files with correct number of pages !?!
Hello,
I have a strange problem. Ever since I have moved the files I'm linking to
in the following code to the classpath, they are downloading as empty files
but *with the correct number of pages*!
Any ideas?
Thanks
class AlarmLink extends Link implements IResourceListener {
private IResource resource;
AlarmLink(String id, final IModel model) {
super(id, model);
resource = new ResourceStreamResource(null) {
@Override
protected IResourceStream getResourceStream() {
File path;
try {
path = new
ClassPathResource("descriptors/hc").getFile();
} catch (IOException exception) {
return null;
}
return new FileResourceStream(new File(path,
getModelObject().getFile()));
}
};
}
public final void onResourceRequested() {
Attributes a = new Attributes(RequestCycle.get().getRequest(),
RequestCycle.get().getResponse(), null);
resource.respond(a);
onLinkClicked();
}
@Override
protected final CharSequence getURL() {
return urlFor(IResourceListener.INTERFACE, null);
}
@Override
public void onClick() {}
@Override
public IModel getBody() {
return PropertyModel.of(getModel(), "label");
}
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.getAttributes().put("target", "_blank");
}
}
