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:

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,

Unfortunately, BIND's logging is verbose but not useful.

No clue.

Other than a minor typo (should be args[0] instead of args[1]), the update 
example works for me, assuming the server is properly configured with the 
zone and TSIG key in the program.

I'm not sure what's confusing about the update program.  It has pretty 
complete help for all of the commands, and the usage to add a single 
record would be something like:

> server <ip address of server>
> zone <zone name>
> add <name> <ttl> <type> <data>
> send

or, as an example:

> server 127.0.0.1
> zone example
> add foo 3600 A 1.2.3.4
> send

If you fix the one character typo in the example, it is working code.

OK, thanks for the usage example with update, that helped. I have code
now that runs and passes its tests. A peculiar thing seems evident
from my experience with this, the dnsjava 2.0.0 classes appear to be
sensitive to how the classes are loaded. I found this when the
simplest thing worked in a command line class (in public static void
main), worked from the command line invoked by a JUnit TestCase but
failed with NullPointerExceptions when the same TestCase was run by
the the maven (v1.0.2) build system I had. A typical stacktrace would
look like this:

    [junit] java.lang.NullPointerException
    [junit]     at org.xbill.DNS.Record.getTypedObject(Record.java:64)
    [junit]     at org.xbill.DNS.Record.getEmptyRecord(Record.java:87)
    [junit]     at org.xbill.DNS.Record.fromString(Record.java:503)
    [junit]     at org.xbill.DNS.Record.fromString(Record.java:527)
    [junit]     at org.xbill.DNS.Update.add(Update.java:136)
    [junit]     at org.xbill.DNS.Update.replace(Update.java:253)

Anway, I worked around it by throwing together an ant build system for
my project and everything worked. Weird.

There have definitely been some problems relating to class loading, and I 
think they should all be solved in 2.0.1 when it's released.

Is 2.0.1a considered a proper release?  What does the 'a' mean?

'alpha'.  It was basically a snapshot release for someone to test.

I'm going to go ahead and do the real 2.0.1 release now.
