Hello,
I've got an exception while trying to save a file.
Exception in thread "main" java.lang.NullPointerException

this is a part of my implemention:
private void combinePdf() throws IOException {
PDDocument sourcePDFDocument = brandedPdf;
OverlayPDF overlay = new OverlayPDF();
overlay.setSourcePDFDocument(sourcePDFDocument);
overlay.setFirstPageOverlay(substitutedTextPdfTitle);
overlay.setFollowerPageOverlay(substitutedTextPdfFollow);
overlay.setStartPage(config.getStartPageFollower());
overlay.setOverlayPosition("foreground");
overlay.processPages();
if (overlay.getSourcePDFDocument().getDocument() == null)
System.out.println("Nix wars");
// overlay.getSourcePDFDocument().save(outputFile);
overlay.getSourcePDFDocument().save(outputFile);
overlay.getSourcePDFDocument().getDocument().close();
overlay.getSourcePDFDocument().close();
}
Please give me an idea why this happens sometimes.
Thanks.
Mit freundlichen Grüßen/Kind regards
