well this isn't really a jboss thing to cover. Put your servlets in a war, add a web.xml to describe to the container where your servlets are and how to access them.
Putting anything in a sub-directory of tomcat will do you no good. It should all be in the jboss path.
If you put a index.jsp in your war can you go to that? And also if you have deployed a war then you will need to go to at least
(where warname is your context unless you have specifically tried to have this not be so)
