I think Paul's point was that if you're deploying a WAR/EAR that won't work,
hence when possible it's best to avoid such things.
It's also cleaner to get the request via ActionContext. Cleaner still by
implementing ServletRequestAware as then being tied to the servlet spec is
stated explicitly.
(I'm also always nervous about using a string literal to identify an attribute
when there's a defined String for it already.)
If the goal is to load a file then putting it on the classpath and loading it
as a resource is cleaner and safer. If it's for writing then I'd be nervous
about that too; seems like it'd be a better idea to write to somewhere outside
of the webapp :/
