index.html welcome page

I believe this is what controls my www.incentto.com in the war
/home/salesrocket/IncenttoPROD/WEB-INF/web.xml
Or maybe /home/incentto/IncenttoPROD/WEB-INF/web.xml

The ultimate SalesRocket.html page to edit for www.incentto.com is:
/opt/tomcat/webapps/IncenttoPROD/SalesRocket.html

I used this to find it:
find /home | xargs grep SalesRocket.html

Need to figure out how to get full control over those pages. I want to install joomla but not sure how the main index page can ref the swf login within the joomla...
