email sending code not working on ubuntu

Question

I need to send email through my web-application to some gmail account. I have written and tested code in windows machine and it works well. it sends emails from windows (Apache tomcat). But not able to send emails when hosted on Ubuntu in same Apache tomcat version.

what i have tried so far is :

tried both the ports 465 and 587
tried to add ports using command sudo ufw allow 465

but i still get same error.

Here is the error stack trace

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
  nested exception is:
    java.net.ConnectException: Connection timed out

Looks like the Server is not reachable. Maybe blocked by a Firewall? — Jens, Aug 17 '16 at 08:43
Thats what i thought and added the ports in firewall but... no use — Anuja, Aug 17 '16 at 08:49
Can you telnet to it outside of your program? If not, it's network. If yes, it's probably authentication issues. — Diego Martinoia, Aug 17 '16 at 08:50
How can i telnet gmail ? could you please give me some link ? i tried this : "telnet smtp.gmail.com" but it just says trying — Anuja, Aug 17 '16 at 08:51
