Hi!
Thank's for replying Tilman. What i want is to merge several different pdf's to
one single document. I have a main document from a file and an adress-database.
I take the main document, put an adress on it. Take the same main document, put
the next adress on it and so on. This is done at "oneDocSerial". At the end of
that loop i want to merge these documents into one single pdf. This single pdf
shall now be displayed for the user and maybe printed out. Not saved to file.
The conversion into InputStream is done only for the reason being able to use
your Example.
You mentioned this were an empty stream:
Compute docPer:
private InputStream oneDocSerial(PDDocument doc) throws IOException {
// do something with doc -> put an adress there
PDStream ps = new PDStream(doc);
InputStream output = ps.createInputStream();
return output;
}
The "doc" in "oneDocSerial" is the main document originally loaded from a file.
Then an adress is added to this document. Could you please tell me how to
convert the result into avalid InputStream to get your example working?
Or is there a directer way to merge the adress-pdf documents into one single
without need using InputStream?
Kind regards,
Siegfried

That is not a PDF. That is an empty stream.

what do you want to do? If you want the input stream of a PDF (which doesn't
make sense if you have the PDF as a file), then do this:
PDDocument.load(new FileInputStream(new File(...)))
