[jdom-interest] Creating a pure text file using XSL

[Laurent Bihanic]

Hi,

You can not use JDOMResult to get anything but XML output from an XSLT 
transformation.
Thus, is your output is either "text" ot "html", you must use a StreamResult.

This is why you get this EmptyStackException from JDOMResult.
