Openfire server pep based avatars , Android client - xmpp

Question

I have setup openfire server and my android clients works well with it except that I am unable to publish avatars , the problem is that the server simply ignores the publish avatar iq packet , no errors , nothing in the log files. I am using standard XMPP pep avatar stanza , please hep
Thankyou for your replies everyone, I found that the issue is with openfire server 3.10 which does not parse the standard XEP 0084 stanza well, infact I found the logs and server was crashing so i modified the IQ as , for example this should be the standard IQ for publishing avatar
<iq type='set' from='juliet#capulet.lit/chamber' id='publish1'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<publish node='urn:xmpp:avatar:data'>
<item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
<data xmlns='urn:xmpp:avatar:data'>
qANQR1DBwU4DX7jmYZnncm...
</data>
</item>
</publish>
</pubsub>
</iq>
but as you can see there is no "to" address in the standard IQ , openfire server would create the pubsub node in DB and crash and would not reply with result asking the user to now publish metadata ,so what i had to do is send this packet and then the standard metadata packet , but then send meta data packet again with a "to" address which would be replied by the server as result that the metadata notification succeded as
standard meta data to be sent to server for the first time ,
<iq type='set' from='juliet#capulet.lit/chamber' id='publish2'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<publish node='urn:xmpp:avatar:metadata'>
<item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
<metadata xmlns='urn:xmpp:avatar:metadata'>
<info bytes='12345'
id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
height='64'
type='image/png'
width='64'/>
</metadata>
</item>
</publish>
</pubsub>
</iq>
and then again like this with addition of "to" address
<iq type='set' from='juliet#capulet.lit/chamber' to="mydomain.com" id='publish2'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<publish node='urn:xmpp:avatar:metadata'>
<item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
<metadata xmlns='urn:xmpp:avatar:metadata'>
<info bytes='12345'
id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
height='64'
type='image/png'
width='64'/>
</metadata>
</item>
</publish>
</pubsub>
</iq>
in the above way avatar publishing is working and Im successfully issuing a notification to other users also
and here is the server crash log incase
