You have to be aware that integrated signing of PDF files requires manipulation of the existing PDF. But the information concerning the PDF document structure (which you need to execute those manipulations) unfortunately (for a streaming model) reside at the end of the document. So the whole PDF must be present on server side and accessible by the code before you can start those manipulations. Your application, therefore, cannot simply stream the request data to the response output stream and immediately forget about it. What you can do, though, is temporarily store the PDF on disc and use a PdfReader constructor/factory method which accepts random access to the PDF. PdfReaders created like that do require way less memory than those working only in memory.
