XOM API for Processing XML with Java

["Michael Kay" <mike AT saxonica.com>]

I don't know the answer I'm afraid - haven't heard anything from Wolfgang
for a while. But the "NoSuchMethodError" tends to suggest that A is calling
B, and A was compiled with a different version of B from the one available
at run-time.

I think Nux makes some fairly low-level of Saxon interfaces, so it would be
a mistake to assume it will work with a later version of Saxon than the one
it was compiled against.

Me neither. This is the great benefit of publishing somewhere like
SourceForge - it's rather more likely to stay around (though nothing is
certain, of course).

I found an unzipped copy on my disk, I've zipped it up and uploaded it to

http://www.saxonica.com/download/nux.rar

I'm afraid I have no idea what state this is in, whether it's the latest
version, complete, etc: but it does include source, and if you want to try
and rebuild from it, you're welcome (as far as I'm concerned, anyway!).
