Send email with attachment which contains byte[] via java mail

I have following byte[] which comes from database.

0x255044462D312E330A25AAABAC

Note: above byte array is sample full file is not here because of length.

UPDATE:

But I am getting like [B@7ffd10fa format

• Before you see code please read here:

When I send bytes which returns getPdfByteStream() method it sends attachment in email like original file. But when I get from database and send it sends corrupted file.

UPDATE:

Entity.class

@Lob
@Column(name = "ATTACHED_FILE")
private byte[] attachedFile;

//getter()/setter();

Code which sends email

 try {
        MimeBodyPart textBodyPart = new MimeBodyPart();
        textBodyPart.setText(content);

       //byte[] bytes = getPDFByteStream(); //Returns byte[] reading local drive file


         **UPDATE:**

        //bytes[] bytes=entity.getAttachedFile(); // It gets value from entity.

        /**
        ** It is getting like "[B@7ffd10fa" format but m storing on database like "0x255044462D312E330A25" format
        **/

        String string="0x255044462D312E330A25";
        byte[] bytes =string.getBytes(Charset.forName("UTF-8"));
        System.out.println("bytes " + bytes.toString());

        DataSource dataSource = new ByteArrayDataSource(bytes, "application/pdf");
        MimeBodyPart pdfBodyPart = new MimeBodyPart();
        pdfBodyPart.setDataHandler(new DataHandler(dataSource));
        pdfBodyPart.setFileName("bankAdminReport.pdf");

        MimeMultipart mimeMultipart = new MimeMultipart();
        mimeMultipart.addBodyPart(textBodyPart);
        mimeMultipart.addBodyPart(pdfBodyPart);

        InternetAddress iaSender = new InternetAddress(sender);
        InternetAddress iaRecipient = new InternetAddress(recipient);

        MimeMessage mimeMessage = new MimeMessage(session);
        mimeMessage.setSender(iaSender);
        mimeMessage.setSubject(subject);
        mimeMessage.setRecipient(Message.RecipientType.TO, iaRecipient);
        mimeMessage.setContent(mimeMultipart);

        Transport.send(mimeMessage);
    } catch (Exception ex) {
        ex.printStackTrace();
    }

getPDFByteStream() method

public static byte[] getPDFByteStream() throws IOException {
    File file = new File("C:\\pdf\\bankAdminReport.pdf");

    byte[] b = new byte[(int) file.length()];
    try {
        FileInputStream fileInputStream = new FileInputStream(file);
        fileInputStream.read(b);
    } catch (FileNotFoundException e) {
        System.out.println("File Not Found.");
        e.printStackTrace();
    } catch (IOException e1) {
        System.out.println("Error Reading The File.");
        e1.printStackTrace();
    }
    return b;
}

Can anyone guide me.

The main problem is when I send file reading from local drive it sends perfectly. but if I send getting from database or any local variable file corrupts.
