setting context-root for web application

This may not be Java related, It is related with JBoss.can anyone explain how to set context-root for a web application? I am looking for a way to configure the application server to allow for downloading certan files through browser.

I am using JBoss 4.0.5.GA.

The link which refers to the file for download, gives me this error(when I right click on that to use option "save target as..":

Internet Explorer cannto download"file name" from"IP address of the computer". Internet Explorer was not able to openthis Internet site. The requested site is either unavailable or cannot be found. Pleasetry again later".

I can see the files created on the hard drive, and they are linked properly. I have also tried using an xml file which sets the context as follows:

<?xml version='1.0' encoding='utf-8'?>

<Context debug="99" docBase="c:\\Fastran" path="\\Fastran" reloadable="true">

</Context>

N.B. I have posted this question earlier too, and am doing that again just to make it more concise. If I try to access "http://ip address/Fastran" even then I can't access that.
