[JDEV] Component failing to push new roster information to client

[Mike Prince]

I'm getting a 503 (Service unavailable) when I try to push a new roster
to a client that's online and available.  In short I'd like to "force"
new users onto a client.

Why am I getting this error?

Here's the low-down...

1) Running JabberD 1.4.2 on XP (argh)
2) Java Component connects up, handshakes, and successfully issues

<xdb from="realtime" to="exodus at localhost" id="1" type="set"
ns="jabber:iq:roster">
<query xmlns="jabber:iq:roster">
	<item jid="woman at localhost" subscription="both" name="woman">
		<group>group</group>
	</item>
	<item jid="carol at localhost" subscription="both" name="carol">
		<group>group</group>
	</item>
	<item jid="man at localhost" subscription="both" name="Mann">
		<group>Snowsports</group>
	</item>
</query>
</xdb>

3) I then try to push the roster to the client (yes, it's connected and
available)

<iq from="realtime" to="exodus at localhost" id="2" type="set">
	<query xmlns="jabber:iq:roster">
		<item jid="woman at localhost" subscription="both"
name="woman">
			<group>group</group>
		</item>
		<item jid="carol at localhost" subscription="both"
name="carol">
			<group>group</group>
		</item>
		<item jid="man at localhost" subscription="both"
name="Mann">
			<group>Snowsports</group>
		</item>
	</query>
</iq>

4) Which generates this error

<iq from='exodus at localhost' to='realtime' id='2' type='error'>
	<query xmlns='jabber:iq:roster'>
		<item jid='woman at localhost' subscription='both'
name='woman'>
			<group>group</group>
		</item>
		<item jid='carol at localhost' subscription='both'
name='carol'>
			<group>group</group>
		</item>
		<item jid='man at localhost' subscription='both'
name='Mann'>
			<group>Snowsports</group>
		</item>
	</query>
	<error code='503'>Service Unavailable</error>
</iq>

5) From JabberD, the debug shows...

Sooooo.... Am I even doing this the right way?  Is there a better way?
How should I signal to the client that the roster should change?

Thanks much,

Mike
