i get this error message
Failure: Messaging Exception: javax.mail.AuthenticationFailedException
How do i solve this?
All help will be greatly appreciated thanks

  1. You do not want to do this sort of thing in JSP which is for view, you need to do it in an object or method called by servlet
  2. You need to do some reading may be this can help
  3. You need to find out how Yahoo enable 3rd parties to use their email services

Oh i see thanks for the help.
Do you have any idea how yahoo will allow that?

Nope, but if you search forum there been already few attempts so maybe some of them got it right, otherwise you need check Yahoo resources
