Re: Access to attachment from Mailet

[Sandeep Chandur Ravi]

Hi Carl,

Yes, it is possible to process a mail attachment from within a mailet.

For example, in your matcher, you can check if your message content is 
an instance of MimeMultipart (assuming the incoming email is multipart 
MIME encoded), and use the javax.mail.internet.MimeBodyPart to check the 
type of attachment (using its getContentType()). Then in your mailet, 
you can do a similar thing and process the attachment as desired.


Example code for matcher:

public Collection match(Mail mail) throws MessagingException {
 if(mail.getMessage().getContent() instanceof MimeMultipart) {
   MimeMultipart multipart = (MimeMultipart) 
mail.getMessage().getContent();
  
   // extract the MimeBodyParts and check for content type if required.

 }

 // if your desired condition is satisfied
 return mail.getRecipients();
}

Hope this helps.

Cheers,
Sandeep

Carl, Here is some code from the service() routine of a mailet I use to 
grab jpg's from attachments:


// Loop through the attachments
//
// Have a look at:
// 
http://java.sun.com/developer/onlineTraining/JavaMail/contents.#GettingAttachments
// for some tips on saving attachements.
//

try {
MimeMessage msg = (MimeMessage) mail.getMessage();
Multipart mp = (Multipart) msg.getContent();
boolean imageFound = false;
for (int j = 0, n = mp.getCount(); j  n; j++) {
Part part = mp.getBodyPart(j);

String disposition = part.getDisposition();
String contentType = part.getContentType();

log(Content Type =  + contentType +  Disposition 
= 
+ disposition);

if (contentType.startsWith(image/jpeg)) {
imageFound = true;
saveImage(user, part);
}
}
if (imageFound) {
sendImageReceived(recipient, sender, user);

} else {
sendImageNotReceived(recipient, sender, user);
}
} catch (Exception e) {
log(Error: , e);
}


Hope this helps.  -- Bud

I notice the link in the code is bad.  It needs a html after the dot:
