By default Xerces doesn't handle streaming data. You need to hand it a
reader that returns from reads with what is available rather than blocking
for the normal cache size of input. If you have the Xerces documentation,
see the Xerces FAQ. One of the questions is how do I parse streaming XML
data and the answer has the source code for a character reader class that
does the trick. If not, go to the Xerces website where you'll find the
BTW, once you get it working let me know. I've been having trouble getting
the character reader to return odd numbers of characters (it seems to slurp
in pairs of characters) which causes some Jabber packets to jam up unless I
artificially inject an extra whitespace. I'd love to know a better
workaround or solution.
