JDOM的实现类和Java开发时需要的包

The Jaxen libraries included here are based on Jaxen 1.0-FCS.  Jaxen 1.0-FCS
was written against JDOM Beta 9, and for Jaxen to support JDOM Beta 10+, we
had to make the following change to org.jaxen.jdom.DocumentNavigator.  The
jaxen-jdom.jar provided here includes this change, and it's the only
difference between the JARs here and the Jaxen 1.0-FCS JARs.
