Here is an example to send an email with attachment from your machine.One common requirement that developers often have is to send notification emails to an application’s users. In the example i demonstrate the basic use of Java mail API to send html formatted email with attachment.
You need following dependencies (JARS) to be able to send an email:
- mail.jar
- activation.jar
Sending email with attachment using JavaMail API
There are total 7 steps for sending attachment with email. They are:
- Get the session object
- compose message
messageBodyPart.setText("This is message body");
- create MimeBodyPart object and set your message text
- create new MimeBodyPart object and set DataHandler object to this object
messageBodyPart = new MimeBodyPart(); String filename = "D:Javasmailapisalary.log"; DataSource source = new FileDataSource(filename); messageBodyPart.setDataHandler(new DataHandler(source)); messageBodyPart.setFileName(filename); multipart.addBodyPart(messageBodyPart);
- create Multipart object and add MimeBodyPart objects to this object
- set the multiplart object to the message object
message.setContent(multipart);
- send message
Create Java Class-
import java.util.*; import javax.mail.*; import javax.mail.internet.*; import javax.activation.*; class SendAttachment{ public static void main(String [] args){ String to="admin@dineshonjava.com";//change accordingly final String user="dineshonjava@gmail.com";//change accordingly final String password="******";//change accordingly //1) get the session object Properties props = new Properties(); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.socketFactory.port", "465"); props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "465"); Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(user,password); } }); //2) compose message try{ MimeMessage message = new MimeMessage(session); message.setFrom(new InternetAddress(user)); message.addRecipient(Message.RecipientType.TO,new InternetAddress(to)); message.setSubject("Salary Aleart"); //3) create MimeBodyPart object and set your message text BodyPart messageBodyPart1 = new MimeBodyPart(); messageBodyPart1.setText("Dear User," + "nn Please find attached file for salary log. This mail tutorial really nice, please try it!!!"); //4) create new MimeBodyPart object and set DataHandler object to this object MimeBodyPart messageBodyPart2 = new MimeBodyPart(); String filename = "D:Javasmailapisalary.log";//change accordingly DataSource source = new FileDataSource(filename); messageBodyPart2.setDataHandler(new DataHandler(source)); messageBodyPart2.setFileName(filename); //5) create Multipart object and add MimeBodyPart objects to this object Multipart multipart = new MimeMultipart(); multipart.addBodyPart(messageBodyPart1); multipart.addBodyPart(messageBodyPart2); //6) set the multiplart object to the message object message.setContent(multipart ); //7) send message Transport.send(message); System.out.println("message sent...."); }catch (MessagingException ex) {ex.printStackTrace();} } }
As you can see in the above example, total 7 steps are followed to send email with attachment. Now run this program by :
