Getting Smackx PubSub working

I've got the following code:

        PubSubManager manager = new PubSubManager(connection, "pubsub.openfire.local");
        LeafNode myNode = (LeafNode) manager.createNode("NewNode", form);

        SimplePayload payload = new SimplePayload("session", "pubsub:NewNode:session", "<sessionId>1234</sessionId>");


        // putting null for id means you let server generate id
        PayloadItem<SimplePayload> item = new PayloadItem<SimplePayload>(null, payload);

        // you could use publish() for asynchronous call
        myNode.send(item);

and I continuously get the following error on trying to send the node value:

conflict(409) at >org.jivesoftware.smackx.pubsub.packet.SyncPacketSend.getReply(SyncPacketSend.java:53) at >org.jivesoftware.smackx.pubsub.packet.SyncPacketSend.getReply(SyncPacketSend.java:61) at >org.jivesoftware.smackx.pubsub.PubSubManager.sendPubsubPacket(PubSubManager.java:324) at >org.jivesoftware.smackx.pubsub.PubSubManager.sendPubsubPacket(PubSubManager.java:318) at org.jivesoftware.smackx.pubsub.PubSubManager.createNode(PubSubManager.java:134) at PubSubPublisher.main(PubSubPublisher.java:33)

Would love any ideas about how to debug, or move forward with this. Thanks.

The node you are trying to create already exists. Call getNode and/or deleteNode first and then createNode. Wrap your code in a try/catch block to handle the XMPPException that may be thrown.

LeafNode myNode = null;
try{
  try{
    LeafNode existingNode = manager.getNode("NewNode");  
    //exists, so delete
    manager.deleteNode("NewNode");
  }catch(XMPPException e){
    //'getNode' threw an exception.
    //so we know that the node did not exist
  }
  myNode = (LeafNode) manager.createNode("NewNode", form);
}catch(XMPPException e){
  System.err.println(e);
}
