Hi Every One,
I am new in smack and this this foum too 
Actually, I want to subscribe for XMPP notifications. What I have done so far is:
ResourceBundle bundle = ResourceBundle.getBundle("com.ef.apps.grc.resources.config");
String JID = bundle.getString("JABBER_ID");
//creating Jabber ID corresponding to whcih node will be subscribed
String myJID = userID + JID;
final String publisherNodeID = "/finesse/api/User/" + userID + "/Dialogs"; PubSubManager mgr = new PubSubManager(connection);
//creating node which subcribes to finesse events
LeafNode node = (LeafNode) mgr.getNode(publisherNodeID);
//an Item that has been, or will be published to a pubsub node. //An Item has several properties that are dependent on the configuration of the node to which it has been or will be published.
//Defines the listener for items being published to a node.
node.addItemEventListener(new ItemEventCoordinator<Item>());
node.subscribe(myJID); //packet filter
//Listener for Finese Notification
PacketFilter filter = new MessageTypeFilter(Message.Type.normal);
connection.addPacketListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
//casting packet into message
Message mes = (Message) packet;
System.out.println("Received Event From Finesse: " + packet.toString());
//casting message into xml containing string
//and passing it for parsing
// to extract caller & calle number
XMLParser.parseXML(mes.toXML(), extension, publisherNodeID);
System.out.println("Parsed XML: " + XMLParser.state);
/*checking if state in the dialog received is equal to ALERTING then send caller and calle numbers to GRC*/
if (XMLParser.state != null && XMLParser.state.equals("ALERTING")) {
//converting caller and calle numbers from dialog
//into query string parsedMessage = "fromAddress=" + XMLParser.fromAddress + "&toAddress=" + XMLParser.toAddress;
} else {
System.out.println("State:" + XMLParser.state);
}
}
}, filter);
Now, I am un-able to understand that this listener method’s will be called automatically whenever there is any notification on the node I have subscribed to ? Or I will have to run this code as servise that will continouly listen for notification on the subscribed node ?
If there is any material on web explaining the complete procedure, kindly share the link.
Thanks in Advance
