Who is calling the backend object, and is it and/or the backend object 
part of the web application?

The point is that ServletContext.getResource(), 
ServletContext.getResourceAsStream(), Class.getResource() and 
Class.getResourceAsStream() can all provide access to a resource within 
a web application using a "path" that is guaranteed to work regardless 
of deployment.  Assuming the backend object is part of the web 
application, a ServletContextListener could pass a ServletContext to the 
backend object during web application initialization, or read the 
properties and pass a Properties object.
