title: finding the tomcat installation directory
body: <p>I get the following message when I access IP provided by my ISP.</p>
  
  <pre><code>If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!
  
  As you may have guessed by now, this is the default Tomcat home page. It can be found on the local filesystem at:
  
  $CATALINA_HOME/webapps/ROOT/index.html
  
  where "$CATALINA_HOME" is the root of the Tomcat installation directory.
  </code></pre>
  
  <p>I want to change this default index.html page. Is there any one unix command to find the location of this index.html?</p>
  
  <p>EDIT:
  I located the ROOT folder. Another issue that I am facing is that my PHP page does not work here. But if I use php phppage.php at command line, it does work as expected.</p>
