Xj3D, X3D configure mouse and keyboard?

If anyone is familiar with Xj3D API... I found this demo code and he is trying to load a x3d xml image from a JFrame, I can compile but can't run due to need to configure the peripherals - mouse and keyboard not sure how to do this. I get this java.lang.reflect.InvocationTargetException?

This leads to the next error in running: SYSTEMID provided is wrong. Something with a Internal stack traceorg.xml.sax.SAXException; I realise this is a sun developers site but the folks at www.web3d.org dont have very good help forums.
