thanks BALUSC
the problem is solved as
ServletOutputStream op = response.getOutputStream();
                    int length = 0;
                    byte[] bbuf = new byte[invoice.getInvoiceFile().length];
                    ByteArrayInputStream arrayInputStream = new ByteArrayInputStream(invoice.getInvoiceFile());
                    DataInputStream in = new DataInputStream(arrayInputStream);
                    while ((in != null) && ((length = in.read(bbuf)) != -1)) {
                         op.write(bbuf, 0, length);
                    }
