It seems, that Tomcat will do a bit of cleanup on the paths you specify in docBase. If I read it correctly, ContextConfig#fixDocBase will convert the base you give to a canonical representation and remove the leading slash. Therefore, if you specify docBase="/" (to indicate the mount point "/" aka root of the filesystem), Tomcat will change it to "", which then (and this is guessing) could lead to a state, Tomcat doesn't know where to find any files. I believe, there is no easy (safe/sane) way to get Tomcat (that is the DefaultServlet) serve the OS-root as you want to have it. There are probably other things you can do, to achieve your goals. Use a real filemanager app inside of Tomcat, or use another lightweight http server (if you really want to use http for this). Python3 has a built-in module http.server, which could be used to do this with a one-liner in shell. But, as others already said: Be careful!
