Servlet can't communicate with 'Database made using XML' !

Iam making an application in which the user logs in by entering
username and password through a Servlet ,

Usernames and passwords are already stored in an XML document on the
server , the Servlet has to just parse the XML document and verify the
username and password

iam using 'Apache Tomcat 4.1.12' and 'JAXP api for XML' processing

THE PROBLEM IS THAT WHILE RUNNING THE SERVLET IT IS THROWING
EXCEPTIONS(NULL POINTER EXCEPTION) THAT IT WAS UNABLE TO PARSE THE XML
FILE !
IT ALSO GIVES 'http-ERROR 500'

PLEASE IF ANY ONE CAN HELP

Please don't use all caps. It makes you look rude.

Anyway, you'll need to show us your code + xml file, otherwise noone here
will be able to tell what you're doing wrong.

Have you tried parsing the xml file in an ordinary class? If you can get it
to work there, then you might try in a servlet. This method will be faster
to try/debug.
