Hi,

Thanks for the hello world example.  I tried it out, I was able to create the node and publish items to the node, and the notification was able to work if the subscriber is the publisher itself.

This works because automatically the publisher automatically becomes a subscriber (I think part of the XEP-0060 specs says so).

If the subscriber is another Jabber contact, then there would need to be some extra code, I think, calling the subscribe(...) method of the Node class.  Please correct me if I'm wrong.

hello,folks

   I have a packet ,(

send：<iq id="V2oVY-12" to="conference.zq" type="get"><query xmlns="http://jabber.org/protocol/disco#items"></query></iq>

and receive：

     <iq type="result" id="V2oVY-12" from="conference.zq" to="admin@zq/zq">
          <query xmlns="http://jabber.org/protocol/disco#items">
            <item jid="sh@conference.zq" name="fun"/>
            <item jid="test@conference.zq" name="news"/>
          </query>
     </iq> )

I want to Publish-Subscribe this packet.If item is changed (e.g. new create ,update or delete),openfire server notified me that ! How can I use smack pubsub ?

  Thanks in advance,

Hello,

I'm trying you example code but this doesn't work.  I get 2 errors.

The first error is with this line I get "type org.jivesoftware.smackx.pubsub.Item does not take parameterstype org.jivesoftware.smackx.pubsub.Item does not take parameters" :

Item<SimplePayload> item = new Item<SimplePayload>(itemId, payload);

The second problems is with this line :

myNode.addItemEventListener(myEventHandler);

Where do you create "myEventHandler" ?  I don't see it in your example.

Thanks for the help!

Just follow the instructions in Smack for how to create a connection to a server from a client application.  That connection is then used as documented in the example.

The example code is pretty much complete for creating a node, subscribing and registering a listener.  The only part not shown is the creation of the connection, since it is standard Smack usage.

1) pubsub.my.openfire.server = pubsub. + hostname used to create connection.  Pubsub is the default service name, just like conference is used to address that service.  For example, there is an XMPP server at igniterealtime.org.  The conference service is addressed as conference.igniterealtime.org and the pubsub service is pubsub.igniterealtime.org (I am not implying that you can access the pubsub.igniterealtime.org).

2) Yes.  In fact, PubsubManager.discoverNodes(), PubSubManager.getSupportedFeatures() and Node.discoverInfo() are all convenience methods for obtaining this information.
