Sending mail attachment using Java

Question

I am trying to send an email using Java and Gmail. I have stored my files on the cloud and the stored files I want to send as an attachment to my email.

It should add those files to this mail and not links of those files.

How I can send such attachments?

Working code, I have used Java Mail 1.4.7 jar

import java.util.Properties; import javax.activation.*; import javax.mail.*;  public class MailProjectClass {  public static void main(String[] args) {      final String username = "[email protected]";     final String password = "your.password";      Properties props = new Properties();     props.put("mail.smtp.auth", true);     props.put("mail.smtp.starttls.enable", true);     props.put("mail.smtp.host", "smtp.gmail.com");     props.put("mail.smtp.port", "587");      Session session = Session.getInstance(props,             new javax.mail.Authenticator() {                 protected PasswordAuthentication getPasswordAuthentication() {                     return new PasswordAuthentication(username, password);                 }             });      try {          Message message = new MimeMessage(session);         message.setFrom(new InternetAddress("[email protected]"));         message.setRecipients(Message.RecipientType.TO,                 InternetAddress.parse("[email protected]"));         message.setSubject("Testing Subject");         message.setText("PFA");          MimeBodyPart messageBodyPart = new MimeBodyPart();          Multipart multipart = new MimeMultipart();                  String file = "path of file to be attached";         String fileName = "attachmentName";         DataSource source = new FileDataSource(file);         messageBodyPart.setDataHandler(new DataHandler(source));         messageBodyPart.setFileName(fileName);         multipart.addBodyPart(messageBodyPart);          message.setContent(multipart);          System.out.println("Sending");          Transport.send(message);          System.out.println("Done");      } catch (MessagingException e) {         e.printStackTrace();     }   } }
