class SimpleMail2 {
    public static void main(String[] args) throws Exception{
        System.out.println("Sending mail...");

        props.setProperty("mail.transport.protocol","smtp");
        props.setProperty("mail.host","smtp.mymailserver.com");
        props.setProperty("mail.user","myuser");
        props.setProperty("mail.password","mypwd");

        Session mailSession = Session.getDefaultInstance(props,null);
        mailSession.setDebug(true);
        Transport transport = mailSession.getTransport();

        MimeMessage message = new MimeMessage(mailSession);
        message.setSubject("HTML  mail with images");
        message.setFrom(new InternetAddress("[emailprotected]"));
        message.addRecipient(Message.RecipientType.TO,new InternetAddress("[emailprotected]"));

        //
        // This HTML mail have to 2 part,the BODY and the embedded image
        //
        MimeMultipart multipart = new MimeMultipart("related");

        // first part  (the html)
        BodyPart messageBodyPart = new MimeBodyPart();
        String htmlText = "<H1>Hello</H1><img src="cid:image">";
        messageBodyPart.setContent(htmlText,"text/html");

        // add it
        multipart.addBodyPart(messageBodyPart);

        // second part (the image)

        messageBodyPart.setDataHandler(new DataHandler(fds));
        messageBodyPart.setHeader("Content-ID","<image>");

        // add it
        multipart.addBodyPart(messageBodyPart);

        // put everything together
        message.setContent(multipart);

        transport.connect();
        transport.sendMessage(message,message.getRecipients(Message.RecipientType.TO));
        transport.close();
