How to deploy an HTML file along with a web application in Tomcat 8?

I have a java web application running on Tomcat 8. The application running on localhost:8080. What I want to do is, deploying an additional html file to tomcat and make it run under localhost:8080/path. How can I do this?

Solution

One solution is to simply deploy a trivial new web application on context path /path serving only that html file. This way you don't need to touch your existing ROOT application:

Create a apache-tomcat/webApps/path/WEB-INF/web.xml :

<?xml version="1.0" encoding="UTF-8"?>

     Additional HTML File
  </description>
</web-app>

Create a apache-tomcat/webApps/path/index.html :

<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
    <h1>Additional HTML File!!!2</h1>
</body>
</html>

Start the tomcat and visit http://localhost:8080/path

This will show you the index.html file.
