Your sample code and stacktrace don't seem to match, but I see what the problem is.  The updatable ResultSet code isn't prepared for handling a SQLXML object.  It's slightly tricky to fix because the code in question is in a JDBC2 class while SQLXML is JDBC4 only.  I'll look into it.

I've put a fix for this into CVS.  I've uploaded a new jar file here:
