Tigase PubSub Component
PubSub Node Presence Protocol

<iq type='set'
    to='pubsub.coffeebean.local'
    id='create1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <create node='message_sink'/>
  </pubsub>
</iq>

After that is done, you need to add SessionManager as a publisher:

<iq type='set'
    to='pubsub.coffeebean.local'
    id='ent2'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub#owner'>
    <affiliations node='message_sink'>
      <affiliation jid='sess-man@coffeebean.local' affiliation='publisher'/>
    </affiliations>
  </pubsub>
</iq>

Finally, the 'msgoffline' offline messages processor must be configured as well

sess-man {
    msgoffline () {
        msg-pubsub-jid = 'pubsub.coffeebean.local'
        msg-pubsub-node = 'message_sink'
        msg-pubsub-publisher = 'sess-man@coffeebean.local'
    }
}
