So you want a physical path like D:\public\files to map-into your URL
space like http://example.com/myapp/files?

Try something like this in your META-INF/context.xml file:

<Context aliases="/files=D:/public/files">
  ...
</Context>

Ref: http://tomcat.apache.org/tomcat-7.0-doc/config/context.html
(search for "aliases").

If/when you upgrade to Tomcat 8, you'll want to replace "aliases" with
something like this:

<Context>
  <Resources>
     <PostResources
        className="org.apache.catalina.webresources.DirResourceSet"
        webAppMount="/files"
        base="D:/public/files" />
  </Resources>
  ...
</Context>

Hope that helps,
