Concerning your first query: the JAXP specification leaves it
implementation-defined exactly what kinds of Java object you can supply to
the setParameter() method. Some products might accept a File object, but I'd
be a little surprised if they did. Saxon will accept any Source object, so
you could do

trans.setParameter("TestFileNm", new StreamSource(new

but this might not work with other products. The most portable way to supply
a document as a parameter is probably to parse the XML file into a DOM and
pass the DOM Document node - unfortunately this might not be the most
efficient approach, since with many XSLT processors their own native tree
implementation is much more efficient than the DOM.
