I have found the key about your problem. you shouldn't add the jar file of dom4j-1.6.1-sources.jar but dom4j-1.x.jar into the project library. Because the jar file's name with sources is pure java file(xx.java), that means it's not compiled at all.

then rebuild your project, it'll work fine.

Hope to help you :)

Apache POI have a handy page listing all the components and their dependencies, you should start by reading that!

Secondly, if you downloaded the binary zip/tarball of Apache POI, then it comes with all of the dependencies you need in the /lib/ and /ooxml-lib/ directories. Make sure you include all the dependencies required from there on your classpath! (You've missed some out, hence the error)
