I am trying to send email from my application .But the exception occurs
javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Unknown SMTP host:
What could be wrong here.Any suggestions?

What do you specify as the SMTP host? It looks like it is not recognized or even empty.

i) Check if you have the required jar files ( mailer.jar, activation.jar, ...) in your class path.
ii) Disable any antivirus program running while trying to send mails. The antivirus may be scanning the ports and block it.
I agree. Here's the link:
