Java Mail... Message.getContent().. can't get Content!

[Anton Pechsherov]

System.out.println("From:"+msg.getFrom()[0]);
       System.out.println(" Subject: " + msg.getSubject());
       System.out.println(" Content: " + msg.getContent());

Show INBOX for [e-mail]
From:=?KOI8-R?B?68nS2sHeIPPB0M/H?= <[e-mail]>
Subject: test
Content: javax.mail.internet.MimeMultipart@787171

I can not get Content of my test message, how i can get it? Sorry of my english

The toString method of the MimeMultipart class doesn't return anything useful, as you can see. You'll need to iterate over all MIME parts using the getCount() and getBodyPart(int) methods. That'll provide you with MimeBodyPart objects that have various methods to give you access to their content.

[Anton Pechsherov]

Do you have an exammple?

[Ulf Dittmer]

Something like this:

MimeMultipart mmp = (MimeMultipart) msg.getContent();
for (int i=0; i<mmp.getCount(); i++) {
    MimeBodyPart mbp = mmp.getBodyPart(i);
    ....
}

If you read the javadocs of those classes you'll probably find other methods that are of interest.

Type mismatch: cannot convert from BodyPart to MimeBodyPart

 
MimeBodyPart mbp = mmp.getBodyPart(i);

That's why I said "Something like..."; I didn't want to do all your work :-)

Do you know how to find out the exact class of an arbitrary Java object? And are you familiar with the concept of casting?

Just remove the "Mime" part from Ulf's code. You should program against the interfaces and abstract classes anyway. Sure, getContent() returns a MimeMultipart now, but in the future that may change to some other Multipart implementation.

And don't forget to check the type of getContent() - it could very well be a String for plain text emails without attachments. So:

Object content = msg.getContent();
if (content instanceof String)
{
    String body = (String)content;
    ...
}
else if (content instanceof Multipart)
{
    Multipart mp = (Multipart)content;
    ...
}

Thanks... this is
