It looks like you don't have all of the dependencies on your classpath.
If you look at http://poi.apache.org/overview.html you'll see that dom4j is a required library when working with the OOXML files. From the exception you got, it seems that you don't have it... If you look in the POI binary download, you should find it in the ooxml-libs subdirectory.
