Hi all.
I need to sign 9 files each of them 1GB long...
I instantiate the reader with
PdfReader reader = new PdfReader(new
RandomAccessFileOrArray(fIn.getAbsolutePath(), false, true),null);
and then I add the signature with:
PdfStamper stp = PdfStamper.createSignature(reader, new
BufferedOutputStream(new FileOutputStream(fOut)), '\0', fTmp, true);
But I get the following OutOfMemory error...
Acrobat reader is able to deal the file very efficiently (small memory
footprint and very fast).
Do you have any idea?
java.lang.OutOfMemoryError: Java heap space
