Handling E-mails With Attachments

[Tiago Fernandez]

Hey fellas,

I'm working with the JavaMail API, and I have to send and receive e-mail with attachments. So far it's ok, but when I receive an e-mail with any attach, I don't get the message body. Otherwise, the message body is being get fine. First I try to get the body, then I get the attachments. What am I doing wrong?

Tks!

private String getMsgBody(Message msg) throws MessagingException, IOException {
String retStr = "";
if (msg.isMimeType("multipart/*")) {
Multipart multipart = (Multipart) msg.getContent();
//check the is a part
if (multipart.getCount() > 0) {
//get the first part
Part p = multipart.getBodyPart(0);
if (p.isMimeType("text/plain") || p.isMimeType("text/html")) {
Object obj = p.getContent();
if (obj instanceof String) {
retStr = (String) obj;
}
}
}
}
else if (msg.isMimeType("text/plain") || msg.isMimeType("text/html")) {
Object obj = msg.getContent();
if (obj instanceof String) {
retStr = (String) obj;
}
}
return retStr;
}

private String[] saveAttachments(Message message) throws Exception {
Multipart multipart = (Multipart) message.getContent();
List attaches = new ArrayList();
for (int i = 0, n = multipart.getCount(); i < n; i++) {
Part part = multipart.getBodyPart(i);
String disposition = part.getDisposition();
if ( (disposition != null) &&
( (disposition.equals(Part.ATTACHMENT) ||
(disposition.equals(Part.INLINE))))) {
attaches.add(part.getFileName());
// Here I save the file into hard disk...
}
}
return (String[]) attaches.toArray(new String[0]);
}

I didn't read your code, but if you assume that it's only a 1 level deep hierarchy, that may be a source of problems; I found that messages were often constructed strangely.

Well, I solved it.

private String getMsgBody(Message msg) throws MessagingException, IOException {
String retStr = "";
Multipart multipart = (Multipart) msg.getContent();
int numberOfParts = multipart.getCount();
if (numberOfParts > 0) {
for (int i = 0; i < numberOfParts; i++) {
Part p = multipart.getBodyPart(i);
String disposition = p.getDisposition();
if (disposition == null) {
MimeBodyPart mbp = (MimeBodyPart) p;
Multipart mp = null;
Object content = mbp.getContent();
if (content instanceof Multipart) {
mp = (Multipart) content;
}
else {
mp = (Multipart) msg.getContent();
}
if (mp.getCount() > 0) {
Part part = mp.getBodyPart(0);
if (part.isMimeType("text/plain") || part.isMimeType("text/html")) {
Object obj = part.getContent();
if (obj instanceof String) {
retStr = (String) obj;
}
}
}
}
}
}
return retStr;
}

Thanks anyway!
