XML : HTTP Status 404 - The requested resource is not available - Web.xml and spring-dispatcher-servlet.xml

I am using Apache Tomcat 8 for running the web application. I am getting an error stating "The requested resource is not available."

URL-> http://localhost:8080/ThreadedDesignPatternAssign/enterPassword.html

However, I was able to successfully test another web application for the same server. I have linked the server to both the projects via Properties -> Project Facets -> Run time.
