But still, I would be happy if somebody answers my questions. ;)

Hi all,
I have a page, and I need to generate a PDF file: after the user presses
a button, then the downloading is being started.
For the PDF-generation I would like to use iText, but I have no idea,
how to create a link to the downloadable content.
I tried to follow UploadDownload wiki page, but got lost by spring
beans. So far I created a DynamicWebResource subclass:
public class PdfFileResource extends DynamicWebResource {
@Override
protected ResourceState getResourceState() {
return new PdfFileResourceState();
}
class PdfFileResourceState extends ResourceState {
@Override
public String getContentType() {
return "application/pdf";
}
@Override
public byte[] getData() {
throw new UnsupportedOperationException("Not supported yet.");
}
}
}
I guess in the PdfFileResource's constructor I need to set the data for
ResourceState, am I right?
The wiki sais also, that in Application#init I need to add the new
SharedResource, so I did that too.
but after that how to use it?
I guessing the follows:
In the Button#onSubmit I should create first the outputstream
(bytearrayoutputstream) for the pdf, after that I should create a new
pdfFileResource with the outputstream.
- But after that, how do I get URL for the newly created resource and
how do I redirect to it?
- While creating the URL for the resource, does it matters which
urlcodingstrategy am I using? (I'm currently using BPRTUCS).
- what does the mountSharedResource do at all? (Is it for only static
resources?)
Any help would be appreciated.
//I looked the archives first, but am still confused, please help
Best Regards,
Peter
