Oracle XDK and FOP 0.20.4 not working...

Question

Hi all,
We have created a sample application with Apache FOP to obtain a PDF document.
But, although it works fine with XERCES and XALAN, it doesn4t work with Oracle XDK, why?
May it be a bug in Oracle XDK? Or do Apache projects implements something non-standard that is used? Or is Oracle who does not implement all the specification?
This is the sample: (in perfect spanish ;-) )
You only should change the file locations and the System.setParameters and libraries to use Apache or Oracle XDK.
Can anybody help us?
Thanks in advance
Jose R.
