Apparently, this is a limitation imposed by Spring.

Then what is the PdfWriter used for?

And a PdfWriter instance.

I don't know how Spring works.
Unlike many of my colleagues that are working with
Spring, I didn't have the time to have a look at
the framework.

>> This is an altered code snippet:

Document document = new Document();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfWriter writer = new PdfWriter(document, baos);
document.open();
// do stuff;
document.close();
baos.writeTo(response.getOutputStream());
