Send e-mail from servlet?

[Bruce Jin]

I want to design my servlet to work as follows:
1)The user key in some value in browser
2)The servlet uses the keyed value to get data from database and then formats a PDF file (in memory)
3)The servlet sends this PDF to a number of people (e-mail address pre-stored)
4)In the meantime, the servlet notifies the browser user.
How do I do the third step: e-mail a file (in memory) to somebody?
Thanks.

This is really a pretty big question, and I'll answer it by pointing you in the right direction: Javamail. Read up on it, because sending mail from a servlet involves setting up an SMTP server among other things, but there is of course tons of information available on how to do it.

Thanks Dave.
I am reading JavaMail. Just wondering if anybody knows some utilities that will do then trick.
