Welcome!  The Java stuff can be found on the Java team at
http://java.jabber.org/, there's not much there yet but join the java dev
list and ask around, there has been some work done on a beans lib and
streaming xml parser.

The way that we are using XML in Jabber doesn't require a "full" XML
parser, there doesn't need to be any validation, no internal DTDs or
entities, no PIs, etc, so a quick-n-dirty custom parser would be enough to
get you by, but in the end it would probably be easier to just find a
decent lightweight XML parser and use it.

I know that there was some difficulty finding an XML parser in Java that
didn't require the full document (it wouldn't process a "stream" on the
fly), so some work has gone into writing a streaming parser around the
internal tokenizer of the XT parser.  Ask on the java-dev list for more
info...

Wonderful, your MSN Java work could be useful for a Java-based MSN
transport on the server side :)
