Help with RosterGroup

Hi All,

I’m implementing a simple messaging system using the Smack API, and I’m trying to work with RosterGroup, but not getting very far. I have two users, userA and userB. userA has a Roster with one entry, userB, userB has a Roster with one entry, userA. There are many more users that userA can send a message to.

I want userA to send a message to userB, given certain conditions, one of which being that userB should be a valid recipient of userA’s message. For this, I thought I’d use RosterGroup and have userB associated with that group:

// create a RosterGroup

rosterA.createGroup(“test_group”);

// add userB to userA’s Roster

String[] groups = {“test_group”};

rosterA.createEntry(username, nickname, groups);

Where:

rosterA is userA’s Roster

username is userB’s username

nickname is userB’s nickname

So userA will send it’s message to userB, provided that userB is in the right group.

But it’s not working. Before sending the message, I iterate through userA’s roster and query each entry’s groups, but although I get userB’s entry, it doesn’t have any RosterGroups associated with it.

Can anyone help me with this?
