Here is the code to send an attachment:

import java.util.Properties;

import javax.mail.*;

import javax.mail.internet.*;

import javax.activation.*;

public class AttachExample {

public static void main (String args[])

throws Exception {

String host = args[0];

String from = args[1];

String to = args[2];

String fileAttachment = args[3];

// Get system properties

Properties props = System.getProperties();

// Setup mail server

props.put("mail.smtp.host", host);

// Get session

Session session =

Session.getInstance(props, null);

// Define message

MimeMessage message =

new MimeMessage(session);

message.setFrom(

new InternetAddress(from));

message.addRecipient(

Message.RecipientType.TO,

new InternetAddress(to));

message.setSubject(

"Hello JavaMail Attachment");

// create the message part

MimeBodyPart messageBodyPart =

new MimeBodyPart();

//fill message

messageBodyPart.setText("Hi");

Multipart multipart = new MimeMultipart();

multipart.addBodyPart(messageBodyPart);

// Part two is attachment

messageBodyPart = new MimeBodyPart();

DataSource source =

new FileDataSource(fileAttachment);

messageBodyPart.setDataHandler(

new DataHandler(source));

messageBodyPart.setFileName(fileAttachment);

multipart.addBodyPart(messageBodyPart);

// Put parts in message

message.setContent(multipart);

// Send the message

Transport.send( message );

}
