how to hide application name in url

i deployed my application on tomcat server.
but url appear in browser is like "www.mydomain.com/applcation_name".
now i want to hide this application name and only want to appear website name.
need help

Install the web app in the ROOT context.

How can i put this app. In root context. I deployed my app. Using parallel plesk panel. On panel i have only browse button to deploy on tomcat..

In Tomcat the ROOT web app directory is in the TOMCAT_HOME/webapps directory, next to all the other web apps.

You want to set up a virtual host.

The documentation in tomcat is quite exhaustive for this:
http://tomcat.apache.org/tomcat-6.0-doc/virtual-hosting-howto.html
