Deployed a java web application. Not able to access the application via the IP address.

I created a Ubuntu 14.04 droplet, and installed tomcat. My droplet’s ip address(from the mail i recieved) is say for example : IP_address.

After that i installed a web application using this tutorial :https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-7-on-ubuntu-14-04-via-apt-get.

I am able to access my application using http://IP_address:8080/myapplication.

Also, I have have connected the IP_address to my domain name using this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-host-name-with-digitalocean.

i.e i have mydomainname.com pointing to IP_address.

Ping from my local system to the domain name gives me a reply mentioning the IP_address.

But when i try to access http://IP_address, my browser just says “This webpage is not available”.

Any help on this would be useful. Thanks in advance.
