session.setDebug(debug);
Message msg = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
addressTo[i] = new InternetAddress(recipients);
msg.setRecipients(Message.RecipientType.TO, addressTo);
msg.setSubject(subject);
BodyPart msgBP = new MimeBodyPart();
msg.setText("Take a look at this");
Multipart mpart = new MimeMultipart();
mpart.addBodyPart(msgBP);
msgBP = new MimeBodyPart();
DataSource src = new FileDataSource(filename);
msgBP.setDataHandler(new DataHandler(src));
msgBP.setFileName(filename);
mpart.addBodyPart(msgBP);
msg.setContent(message, "text/plain");
msg.setContent(mpart);

You're creating a body part for the attachment, but you also need to
create a body part for the main text of your message. See the sendfile.java
demo program included with JavaMail for an example.
