Question: Sample code for sending multipart mail using JavaMail.

Answer: Multipart is like a container that holds one or more body parts. When u send a multipart mail firstly create a Multipart class object and then create BodyPart class object, set text in BodyPart class object and add all BodyPart class object in Multipart class object and send the message. Class Multipart that we will use in this code is an abstract class. Method used in this program of Multipart class is:

void addBodyPart(BodyPart part);

This method is used to add parts in multipart.


package com.withoutbook.common;

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class SendMultipartMail {

public static void main(String args[]) throws Exception {

String host = "192.168.10.110";
String from = "test@localhost";
String to = "arindam@localhost";

Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", host);

Session session = Session.getDefaultInstance(properties);

Message msg = new MimeMessage(session);

msg.setFrom(new InternetAddress(from));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject("MultiPart Mail");

Multipart multipart = new MimeMultipart();

BodyPart part1 = new MimeBodyPart();
part1.setText("This is multipart mail and you read part1......");

BodyPart part2 = new MimeBodyPart();
part2.setText("This is multipart mail and you read part2......");

multipart.addBodyPart(part1);
multipart.addBodyPart(part2);

msg.setContent(multipart);

Transport.send(msg);
System.out.println("Message send....");
}
}
