reagrding smtp and error

[Kirteelokiya]

hello amay, kirtee here.
as i was searching for some src code for projects, I found urs to be simple and understandable.
And as u mentionend in readme file , just run Application.java and give that url in browser. I did the same, bt it is giving me an error as application failed to start. Also while running in browser im getting 404 not found err and it is redirecting to powered by petty verison.
i think the error is regarding smtp bcz i hv not used till this date n in proj smtp port username n passwrd is mntion in application properties.
So can u help me in solving the errror?
