Yes, it does look like your components.xml isn't being read correctly - it should now display 12:05:08,210 INFO [MailSession] Creating JavaMail Session (smtp.gmail.com:465) (the problem with the session-jndi-name approach is that control of the mail session is no longer in Seam and so I don't know the debug output as well ;) ) . You should turn on debug for JavaMail in components.xml anyway <mail:mail-session host="smtp.gmail.com" port="465" username="martin.krajci" password="xxx" ssl="true" debug="true"/> It's very obvious when debug is turned on - lots of stuff is spewed to the console. So, check that your components.xml has been placed in war/WEB-INF/components.xml in your deployed project.
