I downloaded poi version 3.0.2-beta1 from svn, because i want to use

I'd check your classpath. That sort of error is most commonly caused by
having an older version of a library (in this case poi) further up the
classpath. So, it's loading the new excel extractor class from the new
jar, but the rest of poi from an old version
