Reading attachments within attachments

Question

Hi,
I tested this code that I found and I was wondering if it's possible to read attachments within attachments. We are receiving forwarded messages that have an attachment of type message. The attachment then has its own attachment of type doc. We can break it into 2 parts but we don't know how to break it into 3 parts. I'm sure this sounds confusing so here is the code example:
Object content = message.getContent();
if (content instanceof Multipart) {
handleMultipart((Multipart)content,msgName, mailFr, mailTo);
} else {
handlePart(message[i],msgName, mailFr, mailTo);
public static void handleMultipart(Multipart multipart, String msgName, String mailFr, String mailTo)
throws MessagingException, IOException {
          for (int i=0, n=multipart.getCount(); i<n; i++) {
                              handlePart(multipart.getBodyPart(i),msgName, mailFr, mailTo);
public static void handlePart(Part part, String msgName, String mailFr, String mailTo)
throws MessagingException, IOException {
String disposition = part.getDisposition();
String contentType = part.getContentType();
if (disposition == null) { if ((contentType.length() >= 10) &&
(contentType.toLowerCase().substring(
0, 10).equals("text/plain"))) {
//part.writeTo(System.out);
} else {
//part.writeTo(System.out);
     saveFile(part.getFileName(), part.getInputStream(),msgName, mailFr, mailTo);
} else if (disposition.equalsIgnoreCase(Part.ATTACHMENT)) {
               saveFile(part.getFileName(), part.getInputStream(),msgName, mailFr, mailTo);
               System.out.println("This is an attachment");
} else if (disposition.equalsIgnoreCase(Part.INLINE)) {
                    saveFile(part.getFileName(), part.getInputStream(),msgName, mailFr, mailTo);

If you have an attachment that's a message, then try to cast it to something of class Message or MimeMessage, then you can get parts from that.
