 public class MailImageFile extends javax.mail.Authenticator {

            public MailImageFile(){}

     public void Mail(String user, String pass) {
        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("abc@gmail.com", "pqr123%");
            }
            });
        try {
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("abc@gmail.com"));
            message.setRecipients(Message.RecipientType.TO,     InternetAddress.parse("xyz@gmail.com"));
    message.setContent(_multipart);
            message.setSubject("Testing Subject");
            message.setContent("Hi...", "text/html; charset=utf-8");

            Transport.send(message);

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }

//Got this solution form here

    private Multipart _multipart; 
_multipart = new MimeMultipart(); 

public void addAttachment(String filename,String subject) throws Exception { 
    BodyPart messageBodyPart = new MimeBodyPart(); 
    DataSource source = new FileDataSource(filename); 
    messageBodyPart.setDataHandler(new DataHandler(source)); 
    messageBodyPart.setFileName(filename); 
    _multipart.addBodyPart(messageBodyPart);

    BodyPart messageBodyPart2 = new MimeBodyPart(); 
    messageBodyPart2.setText(subject); 

    _multipart.addBodyPart(messageBodyPart2); 
} 


    }
