Here is the code:
Session _gSession = null;
MimeMessage message = null;
Properties props = new Properties();
props.put("mail.smtp.host", smtpHost);
_gSession = javax.mail.Session.getInstance(props, null);
message = new MimeMessage(_gSession);
message.setFrom(new InternetAddress(emailSender , emailSender));
InternetAddress ia[] = new InternetAddress[1];
ia[0] = new InternetAddress(emailReceiver, emailReceiver);
message.setRecipients(Message.RecipientType.TO, ia);
message.setSubject("Test Encoding Attached File");
message.saveChanges();
BodyPart messageBodyPart = new MimeBodyPart();
DataSource fds = new FileDataSource("Big5_Code.txt");
messageBodyPart.setDataHandler(new DataHandler(fds));
messageBodyPart.addHeader("Content-ID","meme");
MimeMultipart multipart = new MimeMultipart("related");
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
transport.connect();
transport.send(message);
