javax.mail.util.ByteArrayDataSource introduced in JavaMail 1.4 and following are some pointers on same

If you use Spring's JavaMail API, you can do this sort of thing fairly easily (or at least, as easily as the JavaMail API allows, which isn't much).

The attachment data can be any of Spring's Resource abstractions, ByteArrayResource is just one of them.

Note that this part of the Spring API stands on its own, it does not require (but does benefit from) the Spring container.

JavaMailSenderImpl mailSender = ... instantiate and configure JavaMailSenderImpl here
final byte[] data = .... this holds my PDF data

mailSender.send(new MimeMessagePreparator() {
   public void prepare(MimeMessage mimeMessage) throws Exception {
      MimeMessageHelper helper = new MimeMessageHelper(mimeMessage);
     // set from, to, subject using helper
     helper.addAttachment("my.pdf", new ByteArrayResource(data));
   } 
});

Please refer the below code :

 if (arrayInputStream != null && arrayInputStream instanceof ByteArrayInputStream) {
    // create the second message part with the attachment from a OutputStrean
    MimeBodyPart attachment= new MimeBodyPart();
    ByteArrayDataSource ds = new ByteArrayDataSource(arrayInputStream, "application/pdf"); 
    attachment.setDataHandler(new DataHandler(ds));
    attachment.setFileName("Report.pdf");
    mimeMultipart.addBodyPart(attachment);
}
