code:

    document.open();
    PDFGenerator.createSummaryTable(document, table, dataList, relPath);
    document.close();
    pdfWriter.close();
    os.flush();
    os.close();

    byte b[] = os.toByteArray();
    ByteArrayOutputStream os1 = new ByteArrayOutputStream();
    PdfReader pdfReader = new PdfReader(b);
    PdfStamper pdfStamper = new PdfStamper(pdfReader, os1);
    pdfStamper.setViewerPreferences(PdfWriter.PDFXNONE);
    pdfStamper.setViewerPreferences(PdfWriter.HideMenubar);
    pdfStamper.setViewerPreferences(PdfWriter.HideToolbar);
    pdfStamper.setViewerPreferences(PdfWriter.HideWindowUI);
    PdfWriter pdfWriter1 = pdfStamper.getWriter();

    pdfWriter1.addJavaScript(getPrintJS());
    pdfReader.close();
    pdfStamper.close();
    os1.flush();
    os1.close();

    OutputStream os2 = httpServletResponse.getOutputStream();
    os2.write(os1.toByteArray());
    os2.flush();
    os2.close();

Answer 1

You Close o1 and after that you read use it again:

os1.close(); //<--- close

OutputStream os2 = httpServletResponse.getOutputStream();
os2.write(os1.toByteArray());  //<--- use os1
