    Hi All,

    public static void downloadFile(String fileName,HttpServletResponse res) throws WebException
    {
    ServletOutputStream outStream = null;

    int bytesRead=0;
    byte [] byteArray = new byte[4096];
    System.out.println("filename===>"+fileName);
    if(null != fileName)
    {
    try
    {
    System.out.println("inside prior to execution download");
    FileInputStream is=new FileInputStream(new File(fileName));
    res.setContentType("image/jpeg");
    outStream = res.getOutputStream();
    bytesRead = is.read(byteArray);
    while (bytesRead!= -1)
    {
    outStream.write(byteArray, 0, bytesRead);
    bytesRead = is.read(byteArray);
    }

    // Flush and close stream
    outStream.flush();
    outStream.close();
    is.close();
    }
    catch (FileNotFoundException e)
    {
    //throw new WebException(e);
    e.printStackTrace();
    }
    catch (IOException e)

    Default Re: IllegalStateException: getOutputStream() has already been called for this respons

    Hi,
    I ll suggest not to use while loop for reading the file data rather create a byte array of file data then at one time write that to response.
