Kaysa, thanks for spending so much time helping me. I disabled the tomcat root application. Now what's happening is at the root of my domain I'm presented with bitnami welcome page (not apache welcome page). So what I did is I removed the tomcat.conf include from httpd.conf, enabled etc/httpd-vhosts.conf include and put the following directive in the hosts file.
ServerAlias www.cognisoftsystems.com ErrorLog /srv/www/cognisoftsystems.com/logs/error.log
CustomLog /srv/www/cognisoftsystems.com/logs/access.log combined
I'm probably missing something though because I still see the bitnami welcome page and when I do domain/cognisoft_site I get a 404. Any ideas on what I'm not doing right?
