Strange java.exe error ... (screendump included 96 KB)

Hello,
I encountered a very strange Java.exe error while testing my servlet.
Here is the screen dump of the aforementioned error:
http://www.shelleysauction.com/db07-22-02.jpg . The error's message is
as follows: "There is no disk in the drive. Please insert a disk into
drive \Device\Harddisk1\DR1."
Would appreciate any help; I don't claim to be any good at this stuff.
All of the information on that page is derived from a database on a
remote intranet machine (including input type, title, descriptions,
etc.). I am not sure if it is a server-side error or a client-side
error as my computer is running the server; another computer is not
possible--I'm a lowly summer intern hired to build a servlet that
interfaces with a database, and I'm not a good programmer.
The only thing I can think of is that I recently began using the
com.oreilly.servlet.* package for its Base64Encoder, Base64Decoder, and
MultiPartRequest methods. That form was working fine for weeks before
then.

Jennica - You're way too hard on yourself.To get such a cool error, you must be a good programmer.

Here's a way to find out if the culprit is your servlet or a pesky browser issue.
Find the IP address of your machine. (I just noticed it's in the screenshot, too.) Then, hop over to another computer and pull up the servlet in another browser. If you get the error over there, you know it's a browser problem (or an issue with the content you're sending to the browser, which is more likely). My guess is that you'll see the message pop up on your machine.
