Yep, was actually cruising the sourcecode and just got this a few
minutes ago.  The servlet context has all the nice methods for file
access ;)

Naturally. I was actually writing a custom taglib to check for the
existence of an asset (graphic file, which is a headshot of a
member) and to use it as a logic:present like tag.  I am actually
going to start a new thread with the sourcecode for that.

There is absolutely no guarantee that webapp resources even *have* a "file
path" at all -- it's perfectly legal for the container to run your
application directly from a WAR file (Tomcat has an option for that), or
dump your static resources into a database, or anywhere else it wants.

To read a resource file like this, use the following:

  InputStream is =
getServletContext().getResourceAsStream("/file.dat");

where the path you pass starts with a slash, and is relative to the
context root.  This is how Struts reads your struts-config.xml file, by
the way, using a typical path like "/WEB-INF/struts-config.xml".

As a side note, placing your data file directly in the context root
directory like this makes it possible for clients to access the file
directly.  If you don't want this (in other words, if the file is only for
internal use by your app), you can put it in /WEB-INF instead.

So even the struts-upload example doesn't get into this, because it
allows you to type in a filename but it treats it as a full unix
path, not a relative path.  How can my struts application work with
files inside the current application.  Surely there must be a way to
deal with real file paths of these files.

Since no one can ever know for certain whether or not his own 
view of creation is the correct one, it is impossible for him 
to know if someone else's is the wrong one.
