That's a common way to handle it, and a small initialization servlet like
this will not use a whole lot of memory so it shouldn't be a problem.

Application scope is the same as ServletContext attributes. So just use
ServletContext.setAttribute and the objects will be available to all
servlets and JSP pages in the same application.
