If the application is not deployed with a war file you can use this code that will return the whole address where the application is running.

//request variable is the Java HTTP servlet request object received from an action 
request.getSession().getServletContext().getRealPath("/");

The code I had given is the one I used in one of my Java EE projects well I didn't deploy my project as a war file due to some reasons

and getting the web application location can be used to get your root directory name
