Yes, that's what I'm trying to do.

I can't figure out how to turn my file name in the file system, c:/GuestbookServlet/work/guestbook/EMCDL43828.zip, into an http:// URL.

I assume that I need to look at something like the context path and/or my web.xml file to determine the exact value of my URL. I can't figure out how to get the leading part of the URL, i.e. the part after http:// and before the file name EMCDL43828.zip.

Can you tell me what I need to do?

Since your servlet can see that file, you can use a scheme such as:

request on:
http://host/servlet/YourServlet

outputs something like this:
    <a
href="servlet/YourServlet?action=getFile&filename=thefilename">thefilename</
a>

And when the user click on that link,  your servlet will get the parameter
action and filename, so you can
go ahead and use the outputStream of the resoponse to send the file back to
the user.

Hope this helps
