tomcat ROOT page

Hi.
I configurated Tomcat to use Apache as Web server. I'm using mod_jk
connector. I redirected context path "/" at apache to tomcat context
path "/" that is ROOT page. Now I would like to change tomcat context
path "/" to be my welcome page whitch source is in directory
webapps/welcome. Welcome page is index.html. I need to change tomcat
ROOT directory.

How can I do that?
Thanx.
Alan
