Greetings Mr James!
If the servlet is installed for your website then you will see /public_html/WEB-INF/ folder under your account if its a linux cpanel server. You will have to upload the .war files there for your application. Once you upload it we just need to restart the tomcat service. and it will automatically deploy your application on server at /usr/local/jakarta/tomcat/webapps/ location and will run your application from there.
For your information the tomcat service will work for your domain only when it points to that server because its a name based service and not IP based.
You will get some more information about the tomcat server from
http://64.38.39.58:8080/ for hosting of eUkhost.
Thank you.
