 [B]Multipart multipart = (Multipart) msg.getContent[/B]();

Well, I guess the return value of msg.getContent( ) is a String. So no, you can't cast it to a Multipart object. Is there a specific reason you'd want to do this?

i want to get attachment

[Nepomuk]

OK, step one would be to tell us where that attachment is. I'd guess it's in the msg object from what you've written but I don't know what type that object has.

Also, you wanting the attachment doesn't explain (at least to me) why you're trying to get your hands on a Multipart object. Is it easier to get the attachment from a Multipart?

I took it from a tutorial

[Nepomuk]

Well, we'll need more context nevertheless. Maybe link to the tutorial or post more code?

OK, I've taken a quick look at the tutorial and it seems you're using a javax.mail.Mess age object. This implements the javax.mail.Part interface which has the getContent() function causing all of this trouble.

This function returns an Object, so it could be anything. Apparently in this case it's a String. I'd recommend using [code=java]System.out.prin tln(msg.toStrin g());[/code] to have a closer look at what exactly it is.
