Update usage?

[Ian K. <spi...@gm...>]

I've been trying to use org.xbill.DNS.Update (using various
permutations, with/without TSIG, TCP, etc) with 2.0.0 and I just get
silent failure (I got NullPointerExceptions with 1.6.6, so maybe
that's a a step up :).
The BIND installation is the one that comes with Mac OS 10.4 (Tiger),
I have a zone "rbl" that is configured to accept updates from
localhost (also tried with a TSIG key).

My test does a query (expecting there to be no record), does an update
and then runs the query again. Running BIND with logging set to
"dynamic", I get the following:

Nov 28 23:50:24.733 zone_timer: zone authors.bind/CH: enter
Nov 28 23:50:24.733 zone_maintenance: zone authors.bind/CH: enter

Any idea what the "request failed: end of file" means and how to deal
with this? The dynamic update example at
http://www.xbill.org/dnsjava/examples.html didn't work. The
update.java in the distribution... it's not clear how to use it and
anyway, it's pretty complicated; I just need to send single short TTL
updates to a BIND server. Any pointers to working code that uses
org.xbill.DNS.Update would be appreciated.

thx,
