How to send conformation e-mail through JSP

I'm working on a project and i want when user click on submit button a conformation email is sent to the user.I need code for that help plz.

if you are talking about sending mail in java here is it Send mail in java class

about confirmation , you will need to generate a random in registration time ,save it to user database record and send it to mail as link like this .

Code:

  http://www.yourdomain.com/confirm.jsp?code=randomcode&&username=username


you will have to read the randomcode and username and compare it with the one in database , if the same , activate the user else show error message .

hope helped .
