Looks like you don’t have all the required jars on your classpath. See the POI Components Page for the list of the Jars you need. (If you downloaded a POI binary release, you’ll have all of them in there, or if you use Maven it’ll download them for you.)

Specifically, in your case, you’re missing the poi-ooxml jar, and possibly its dependencies too – see the components page for the list of those.
