코드 :

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

당신 닫기 O1, 그 후 다시 사용 읽어

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

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