Presumably this doesn't change, right?  You could either store it as a 
constant (public static final String) of the servlet or as a web.xml 
context-parameter.

You can get various parts of the URI from the HttpServletRequest in that 
particular servlet, since presumably the request contains the URL that 
was used to fetch the servlet.  But doesn't sound like what you are 
looking for (a way to determine the URL from within other classes, not 
the servlet).
