Trouble receiving multipart mime messages

Question

I am encountering a problem which has me perplexed... I am attempting to create and send a simple multipart mime message through an smtp server which requires authentication. The thing is the mail gets delivered OK, but nothing appears in the body of the message nor are there any attachments. My code follows, wonder if anyone has any ideas... A full day of searching though Sun documentation, forums and internet surfing has not given me any help... sigh.. Thanks, Marc...
private void sendEmail(
     String emailURL,
     String notes) {
     String to = emailURL;
     String from = "[email protected]";
     String smtpHost = "mail.myservername.com";
     String user = "myId";
     String password = "myPassword";
     boolean debug = true;
     // create some properties and get the default Session
     Properties props = new Properties();
     props.put("mail.smtp.host", smtpHost);
     props.put("mail.smtp.auth", "true");
     Session session = Session.getDefaultInstance(props, null);
     session.setDebug(debug);
     try {
          // create a message
          MimeMessage msg = new MimeMessage(session);
          msg.setFrom(new InternetAddress(from));
          InternetAddress[] address = { new InternetAddress(to)};
          msg.setRecipients(Message.RecipientType.TO, address);
          msg.setSubject("Welcome to JavaMail");
          msg.setSentDate(new Date());
          // create and fill the first message part
          MimeBodyPart mbp1 = new MimeBodyPart();
          mbp1.setText(notes);
          mbp1.addHeaderLine("Content-Type: text/plain; charset=\"iso-8859-1\"");
          mbp1.addHeaderLine("Content-Transfer-Encoding: quoted-printable");
          // create and fill the second message part
          MimeBodyPart mbp2 = new MimeBodyPart();
          // Use setText(text, charset), to show it off !
          mbp2.setText("Eventually I plan to attach an image here");
          mbp2.addHeaderLine("Content-Type: text/plain; charset=\"iso-8859-1\"");
          mbp2.addHeaderLine("Content-Transfer-Encoding: quoted-printable");
          // create the Multipart and its parts to it
          MimeMultipart mp = new MimeMultipart("mixed");
          mp.addBodyPart(mbp1);
          mp.addBodyPart(mbp2);
          // add the Multipart to the message
          msg.setContent(mp);
          msg.saveChanges();
          // send the message
          javax.mail.Transport transport = session.getTransport("smtp");
          transport.connect(smtpHost, user, password);
          transport.sendMessage(msg, address);
          transport.close();
     } catch (MessagingException mex) {
          handleException(mex);
          Exception ex = null;
          if ((ex = mex.getNextException()) != null) {
               handleException(ex);

OH NEVER MIND!!!! What a NASTY NASTY NASTY trap! Shame on Sun and their design/implementation of JavaMail!!!! I didn't have the activation jar file installed on my server.... Gives no errors, no warnings, no exceptions are thrown! Absolutely no clue whatsoever that it is missing!!!
