Shirley,
It looks like you are already calling a folder, just not the right one. Look to see where you are defining your folder and change it.
If you are using oreilly's package then the upload directory is defined as an init-parameter in the webapp your
servlet is currently in. If this isn't the case then I'm not sure where your upload dir is defined.
Hope this helps,
