password-protected servlet

Dear friends,
I have been unable to get the password-protected servlet from Marty Hall's Core Servlets and JSPs to work. I think my trouble is I don't know how to pass the passwords.Properties file to the servlet.
My problem is: the password does not give me access to the servlet.It appears I have not been successful in passing the
user/password values to the servlet even though I tried.
Please help, you may not have to look at the long code. Thanks!
I have a file named: passwords.Properties which contains a few
username/password pairS and it is located in a local folder
(C:\LocalFolder\passwords.Properties) and looks like this:
(Note it is built with a java class and opened with TextPad)

Now,in my XML file I set servlet init parameter passwordFile as follows:

Thanks to those who looked at this message. I have figured out
my problem so don't look at those ugly code again!
