        Iterator<PdfReader> iteratorPDFReader = readers.iterator();

        // Loop through the PDF files and add to the output.
        while (iteratorPDFReader.hasNext()) {
            PdfReader pdfReader = iteratorPDFReader.next();

            // Create a new page in the target for each source page.
            while (pageOfCurrentReaderPDF < pdfReader.getNumberOfPages()) {
                document.newPage();
                pageOfCurrentReaderPDF++;

Answer 1

Please download chapter 6 of my book and take a look at table 6.1. You're making the mistake merging two documents using PdfWriter instead of using PdfCopy as documented. Take a look at listing 6.22 to find out how to add page numbers when using PdfCopy.

i used "PdfCopyFields" Snippet as follows :

public static boolean concatPDFFiles(List<String> listOfFiles,
        String outputfilepath) throws FileNotFoundException, DocumentException {
    PdfCopyFields copy = null;
    try {
        copy = new PdfCopyFields(new FileOutputStream(outputfilepath));
    } catch (DocumentException ex) {
        Logger.getLogger(MergerGoogleDocsToPDF.class.getName()).log(Level.SEVERE, null, ex);
    }
    try {
        for (String fileName : listOfFiles) {
            PdfReader reader1 = new PdfReader(fileName);
            copy.addDocument(reader1);
        }
    } catch (IOException ex) {
        Logger.getLogger(MergerGoogleDocsToPDF.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        copy.close();
    }
    if (new File(outputfilepath).exists()) {
        double bytes = new File(outputfilepath).length();
        //double kilobytes = (bytes / 1024);
        if (bytes != 0) {
            return true;
        } else {
            return false;
        }
    } else {
        return false;
    }
}
