Unable to get the Presence using Smack API

Hi all,

I am new to smack API. I am trying to develop a chat application where I was trying for setting and getting the presence.

When I change the presence of a user, its working perfectly fine and it is getting reflected in the Openfire Server.

But when I tries to get the Presence of a user, I am always getting the status as **’**unavailable’ even if his presence in openfire is showing as

'available’.

I am using the following code to set the status.

Presence presence = new Presence(Presence.Type.available);

presence.setMode(Presence.Mode.available);
presence.setStatus(“available”);

connection.sendPacket(presence);

I am using the Roster class to get the presence as follows.

Roster roster = avatar.getRoster();
Collection entries = roster.getEntries();

for(RosterEntry rosterEntry: entries) {
String user = rosterEntry.getUser();

Presence presence = roster.getPresence(user);

System.out.println("Presence : "+presence); // 1
System.out.println("Presence type: "+presence.getType()); // 2
System.out.println("Presence mode: "+presence.getMode()); // 3

}

Line No 1 alwasys gives ‘unavailable’ while line number 2 and 3 always give null

I am not able to figure out the cause of this problem. Please help me to resolve this issue.

Thanks in advance.

Vinu.
