Deploying java web application on Elastic Beanstalk gives Error : HTTP Status 404 after the login page

I am deploying a war file on Elastic Beanstalk for the first time. I followed all the necessary documents of amazon for doing so. I have a web application similar to dropbox (it gives a platform for any user to upload and download the images. The images are stored in S3 and the CloudFront is used for serving the url. I have used Amazon RDS(MySQL) as the database). The application runs perfectly fine on the local machine. After deploying on the Elastic Beanstalk, it takes me to the main login page but after clicking on any other link on the main login page, it gives me a 404 Error saying that "The requested resource is not available"

I followed the documentation : http://ift.tt/1uWeBxP

Any help on solving this error would be great. Thank you.
