PDF attachment appears inline

Question

I've been struggling with this for two days now. So, I need some input. I have followed the JavaMail example for attaching a file, but it appears inline instead, looking like the pasted content below.
I'm doing the typical:
MimeBodyPart mbp2 = new MimeBodyPart();
// attach the file to the message
FileDataSource fds = new FileDataSource(filename);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(fds.getName());
// create the Multipart and add its parts to it
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);Thanks for any help,
Ron

Answer 1

Thanks, DrClap. I appreciate the input. I probably just included a bad example of the many variations of the code that I've tried. So, let me paste here the fuller version of the code and the javamail debug output. I've played with those headers in every way I can think of. It still goes inline. Argggh!
public class SendMailWithAttachment
     private String     from;
     private String     to;
     private String     subject;
     private String     text;
     private String     fileName;
     public SendMailWithAttachment(String from, String to, String subject, String text, String fileName)
          this.from = from;
          this.to = to;
          this.subject = subject;
          this.text = text;
          this.fileName = fileName;
     public void send()
          boolean debug = true;
          // create some properties and get the default Session
          Properties props = System.getProperties();
          props.put("mail.smtp.host", "smtp.xxx.com");
          Session session = Session.getInstance(props, null);
          session.setDebug(debug);
          try
               // create a message
               MimeMessage msg = new MimeMessage(session);
               msg.setFrom(new InternetAddress(from));
               msg.addRecipient(RecipientType.TO, new InternetAddress("[email protected]"));
               msg.setSubject(subject);
               // create the text message part
               MimeBodyPart mbp1 = new MimeBodyPart();
               mbp1.setText(text);
               mbp1.setHeader("MIME-Version", "1.0");
               mbp1.setHeader("Content-Type", "text/plain; charset='iso-8859-1'");
               // create the pdf attachment part
               MimeBodyPart mbp2 = new MimeBodyPart();
               FileDataSource fds = new FileDataSource(fileName);
               mbp2.setDataHandler(new DataHandler(fds));
               mbp2.setFileName(fds.getName());

               mbp2.setHeader("Content-Disposition", "attachment");
               mbp2.setHeader("Content-Transfer-Encoding", "base64");
               // create the Multipart and add its parts to it
               Multipart mp = new MimeMultipart();
               mp.addBodyPart(mbp1);
               mp.addBodyPart(mbp2);
               // add the Multipart to the message
               msg.setContent(mp);
               // add headers for message
               msg.setHeader("MIME-Version", "1.0");
               msg.setHeader("Content-Type", "multipart/mixed");
               msg.setHeader("X-MS-Has-Attach", "yes");
               // set the Date: header
               msg.setSentDate(new Date());
               msg.saveChanges();
               // send the message
               Transport.send(msg);
          } catch (MessagingException mex)
               mex.printStackTrace();
               Exception ex = null;
