We have a external application, which sends us a email with attachment. In case of contentType Multipart : we are able to parse and process the attachment.
But sometime they send mail with contentType text/plain ( message.getContent() is null), we are not able to get the attachment & email body from message obj.
Sender can't fix the content type to multipart, we have to accommodate it on receiver end.
We are using JavaMail API 1.5,tried apache commons mail util but it only works when you have object in message.getContent()
Folder emailFolder = store.getFolder("INBOX"); emailFolder.open(Folder.READ_ONLY);
Message[] messages = emailFolder.getMessages(); System.out.println("Total Message" + messages.length);
for (int i = 0; i < messages.length; i++) { Message message = messages[i];
Multipart multipart = (Multipart) message.getContent();
for(int k = 0; k < multipart.getCount(); k++){
BodyPart bodyPart = multipart.getBodyPart(k);
InputStream stream =
(InputStream) bodyPart.getInputStream();
}
}

If the content type is text/plain, there is no attachment.
And if message.getContent() is returning null, there's probably no message content either, or something is wrong with the formatting of the message. Post the raw MIME content of the message and I can help you figure what's wrong with the message.
