The problem with this approach is that when you upgrade the war file
the files will be deleted.
I believe It is better to save the files outside the web app and
deliver them either with a symbolic link from within your war file or
using a reader servlet.

Subject: File system resource for static content
Hello users,
I'm trying to find the best practice way for implementing the
following: I want a servlet to perform file uploads and to store the
files in the local filesystem. This part is not that hard to do as
i'm
currently writing into the javax.servlet.context.tempdir.
The problem is that i need to store the files in a directory, that
will be accessible from the web. My tutor at university gave me the
hint that this is best done with a resource which points to a local
directory and that's mapped to the webapp.
So I imagine that http://localhost:8080/WebTest/Upload is my servlet
mapping and that http://localhost:8080/WebTest/files/ points to this
resource.
I do something very similar using apache commons upload project.
I have a separate files directory in my webapp directory and I use
the following code to
initialize a path to save my uploaded files:
ServletContext sc = getServletContext();
String path = sc.getRealPath("/files");
I can then access a file in the that files directory via
http://server:8080/appname/files/filename

But all my research in the documentation did not bring any success. I
know that i can specify resources in the context.xml, but not how I
specify the path on the local system or how to do the mapping... If
anyone already did this and can provide me with configuration
examples, I'd very much appreciate it.
I am using Tomcat 5.5 on Linux (not the pre-packaged), the
application
is deployed as war, my context.xml is located in META-INF
------------------------------------------------------------ <?xml
version="1.0" encoding="UTF-8"?> <Context privileged="true"
antiResourceLocking="false"
antiJARLocking="false"
path="WebTest"
/>
-------------------------------------------------------------
My web.xml is the following:
-------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
