title: Change default tomcat7 webpage to my app
body: <p>How can I display my application as a default webpage? (currently there is default tomcat website)
  Let say my domain is:</p>
  
  <pre><code> http://mywebsite.com
  </code></pre>
  
  <p>When I type this in my browser I have tomcat default website with links to manager etc.
  My application is avaiable from:</p>
  
  <pre><code> http://mywebsite.com/coolapp
  </code></pre>
  
  <p>Is it possible to set my app to be displayed instead of that default tomcat website?</p>
  
  <p>edit:
  sorry forgot to mention it must be in folder coolapp so I cant deploy this as something else. Maybe it's possible to set that coolapp became root folder?</p>
