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.
