It seems like many methods are removed with each version of PDFBox. So that code will not work on PDFBox 2.0.7.

Overlay overlay = new Overlay();
overlay.setInputPDF(realDoc);
// ** The method setOutputFile(String) is undefined for the type Overlay ** 
overlay.setOutputFile("final.pdf")

Instead, use void org.apache.pdfbox.pdmodel.PDDocument.save(String fileName), I think:

PDDocument realDoc = PDDocument.load(new File("originaldocument.pdf"));
    //the above is the document you want to watermark
    //for all the pages, you can add overlay guide, indicating watermark the original pages with the watermark document.

HashMap overlayGuide = new HashMap();
    for(int i=0; i

Edit: I am using org.apache.pdfbox.tools.OverlayPDF for overlays now and it works just fine. The code looks like this:

String[] overlayArgs = {"C:/Examples/foreground.pdf", "C:/Examples/background.pdf", "C:/Examples/resulting.pdf"};
OverlayPDF.main(overlayArgs);
System.out.println("Overlay finished.");
