To convert pdf to byteArray :

public byte[] pdfToByte(String filePath)throws JRException {

         File file = new File();
         FileInputStream fileInputStream;
         byte[] data = null;
         byte[] finalData = null;
         ByteArrayOutputStream byteArrayOutputStream = null;

         try {
            fileInputStream = new FileInputStream(file);
            data = new byte[(int)file.length()];
            finalData = new byte[(int)file.length()];
            byteArrayOutputStream = new ByteArrayOutputStream();

            fileInputStream.read(data);
            byteArrayOutputStream.write(data);
            finalData = byteArrayOutputStream.toByteArray();

            fileInputStream.close(); 

        } catch (FileNotFoundException e) {
            LOGGER.info("File not found" + e);
        } catch (IOException e) {
            LOGGER.info("IO exception" + e);
        }

        return finalData;

    }
